+

+KernelVersion:	4.20
+Description:
+		Specify a software pattern for the LED, that supports altering
+		the brightness for the specified duration with one software
+		timer. It can do gradual dimming and step change of brightness.
+
+		The pattern is given by a series of tuples, of brightness and
+		duration (ms). The LED is expected to traverse the series and
+		each brightness value for the specified duration. Duration of
+		0 means brightness should immediately change to new value, and
+		writing malformed pattern deactivates any active one.
+
+		1. For gradual dimming, the dimming interval now is set as 50
+		milliseconds. So the tuple with duration less than dimming
+		interval (50ms) is treated as a step change of brightness,
+		i.e. the subsequent brightness will be applied without adding
+		intervening dimming intervals.
+
+		The gradual dimming format of the software pattern values should be:
+		"brightness_1 duration_1 brightness_2 duration_2 brightness_3
+		duration_3 ...". For example:
+
+		echo 0 1000 255 2000 > pattern
+
+		It will make the LED go gradually from zero-intensity to max (255)
+		intensity in 1000 milliseconds, then back to zero intensity in 2000
+		milliseconds:
+
+		LED brightness
+		    ^
+		255-|       / \            / \            /
+		    |      /    \         /    \         /

+		  0-|   /             \/             \/
+		    +---0----1----2----3----4----5----6------------> time (s)
+
+		2. To make the LED go instantly from one brigntess value to another,
+		we should use use zero-time lengths (the brightness must be same as
+		the previous tuple's). So the format should be:
+		"brightness_1 duration_1 brightness_1 0 brightness_2 duration_2
+		brightness_2 0 ...". For example:
+
+		echo 0 1000 0 0 255 2000 255 0 > pattern
+
+		It will make the LED stay off for one second, then stay at max brightness
+		for two seconds:

-<p>
-Perhaps you have an RCU protected data structure that is accessed from
-RCU read-side critical sections, from softirq handlers, and from
-hardware interrupt handlers.
-That is three flavors of RCU, the normal flavor, the bottom-half flavor,
-and the sched flavor.
-How to wait for a compound grace period?
-
-<p>
-The best approach is usually to &ldquo;just say no!&rdquo; and
-insert <tt>rcu_read_lock()</tt> and <tt>rcu_read_unlock()</tt>
-around each RCU read-side critical section, regardless of what
-environment it happens to be in.
-But suppose that some of the RCU read-side critical sections are
-on extremely hot code paths, and that use of <tt>CONFIG_PREEMPT=n</tt>
-is not a viable option, so that <tt>rcu_read_lock()</tt> and
-<tt>rcu_read_unlock()</tt> are not free.
-What then?
-
-<p>
-You <i>could</i> wait on all three grace periods in succession, as follows:
-
-<blockquote>
-<pre>
- 1 synchronize_rcu();
- 2 synchronize_rcu_bh();
- 3 synchronize_sched();
-</pre>
-</blockquote>
-
-<p>
-This works, but triples the update-side latency penalty.
-In cases where this is not acceptable, <tt>synchronize_rcu_mult()</tt>
-may be used to wait on all three flavors of grace period concurrently:
-
-<blockquote>
-<pre>
- 1 synchronize_rcu_mult(call_rcu, call_rcu_bh, call_rcu_sched);
-</pre>
-</blockquote>
-
-<p>
-But what if it is necessary to also wait on SRCU?
-This can be done as follows:
-
-<blockquote>
-<pre>
- 1 static void call_my_srcu(struct rcu_head *head,
- 2        void (*func)(struct rcu_head *head))
- 3 {
- 4   call_srcu(&amp;my_srcu, head, func);
- 5 }
- 6
- 7 synchronize_rcu_mult(call_rcu, call_rcu_bh, call_rcu_sched, call_my_srcu);
-</pre>
-</blockquote>
-
-<p>
-If you needed to wait on multiple different flavors of SRCU
-(but why???), you would need to create a wrapper function resembling
-<tt>call_my_srcu()</tt> for each SRCU flavor.
-

-
-<p>
-Again, it is usually better to adjust the RCU read-side critical sections
-to use a single flavor of RCU, but when this is not feasible, you can use
-<tt>synchronize_rcu_mult()</tt>.
+In <tt>CONFIG_PREEMPT=n</tt> kernels, trampolines cannot be preempted,

+<tt>synchronize_rcu()</tt>, and
+<tt>rcu_barrier()</tt>, respectively.
+In <tt>CONFIG_PREEMPT=y</tt> kernels, trampolines can be preempted,

+ext4 General Information
+========================
+
+Ext4 is an advanced level of the ext3 filesystem which incorporates
+scalability and reliability enhancements for supporting large filesystems
+(64 bit) in keeping with increasing disk capacities and state-of-the-art
+feature requirements.
+
+Mailing list:	linux-ext4@vger.kernel.org
+Web site:	http://ext4.wiki.kernel.org
+
+
+Quick usage instructions
+========================
+
+Note: More extensive information for getting started with ext4 can be
+found at the ext4 wiki site at the URL:
+http://ext4.wiki.kernel.org/index.php/Ext4_Howto
+
+  - The latest version of e2fsprogs can be found at:
+
+    https://www.kernel.org/pub/linux/kernel/people/tytso/e2fsprogs/
+
+	or
+
+    http://sourceforge.net/project/showfiles.php?group_id=2406
+
+	or grab the latest git repository from:
+
+   https://git.kernel.org/pub/scm/fs/ext2/e2fsprogs.git
+
+  - Create a new filesystem using the ext4 filesystem type:
+
+        # mke2fs -t ext4 /dev/hda1
+
+    Or to configure an existing ext3 filesystem to support extents:
+
+	# tune2fs -O extents /dev/hda1
+
+    If the filesystem was created with 128 byte inodes, it can be
+    converted to use 256 byte for greater efficiency via:
+
+        # tune2fs -I 256 /dev/hda1
+
+  - Mounting:
+
+	# mount -t ext4 /dev/hda1 /wherever
+
+  - When comparing performance with other filesystems, it's always
+    important to try multiple workloads; very often a subtle change in a
+    workload parameter can completely change the ranking of which
+    filesystems do well compared to others.  When comparing versus ext3,
+    note that ext4 enables write barriers by default, while ext3 does
+    not enable write barriers by default.  So it is useful to use
+    explicitly specify whether barriers are enabled or not when via the
+    '-o barriers=[0|1]' mount option for both ext3 and ext4 filesystems
+    for a fair comparison.  When tuning ext3 for best benchmark numbers,
+    it is often worthwhile to try changing the data journaling mode; '-o
+    data=writeback' can be faster for some workloads.  (Note however that
+    running mounted with data=writeback can potentially leave stale data
+    exposed in recently written files in case of an unclean shutdown,
+    which could be a security exposure in some situations.)  Configuring
+    the filesystem with a large journal can also be helpful for
+    metadata-intensive workloads.
+
+Features
+========
+
+Currently Available
+-------------------
+
+* ability to use filesystems > 16TB (e2fsprogs support not available yet)
+* extent format reduces metadata overhead (RAM, IO for access, transactions)
+* extent format more robust in face of on-disk corruption due to magics,
+* internal redundancy in tree
+* improved file allocation (multi-block alloc)
+* lift 32000 subdirectory limit imposed by i_links_count[1]
+* nsec timestamps for mtime, atime, ctime, create time
+* inode version field on disk (NFSv4, Lustre)
+* reduced e2fsck time via uninit_bg feature
+* journal checksumming for robustness, performance
+* persistent file preallocation (e.g for streaming media, databases)
+* ability to pack bitmaps and inode tables into larger virtual groups via the
+  flex_bg feature
+* large file support
+* inode allocation using large virtual block groups via flex_bg
+* delayed allocation
+* large block (up to pagesize) support
+* efficient new ordered mode in JBD2 and ext4 (avoid using buffer head to force
+  the ordering)
+
+[1] Filesystems with a block size of 1k may see a limit imposed by the
+directory hash tree having a maximum depth of two.
+
+Options
+=======
+
+When mounting an ext4 filesystem, the following option are accepted:
+(*) == default
+
+  ro
+        Mount filesystem read only. Note that ext4 will replay the journal (and
+        thus write to the partition) even when mounted "read only". The mount
+        options "ro,noload" can be used to prevent writes to the filesystem.
+
+  journal_checksum
+        Enable checksumming of the journal transactions.  This will allow the
+        recovery code in e2fsck and the kernel to detect corruption in the
+        kernel.  It is a compatible change and will be ignored by older
+        kernels.
+
+  journal_async_commit
+        Commit block can be written to disk without waiting for descriptor
+        blocks. If enabled older kernels cannot mount the device. This will
+        enable 'journal_checksum' internally.
+
+  journal_path=path, journal_dev=devnum
+        When the external journal device's major/minor numbers have changed,
+        these options allow the user to specify the new journal location.  The
+        journal device is identified through either its new major/minor numbers
+        encoded in devnum, or via a path to the device.
+
+  norecovery, noload
+        Don't load the journal on mounting.  Note that if the filesystem was
+        not unmounted cleanly, skipping the journal replay will lead to the
+        filesystem containing inconsistencies that can lead to any number of
+        problems.
+
+  data=journal
+        All data are committed into the journal prior to being written into the
+        main file system.  Enabling this mode will disable delayed allocation
+        and O_DIRECT support.
+
+  data=ordered	(*)
+        All data are forced directly out to the main file system prior to its
+        metadata being committed to the journal.
+
+  data=writeback
+        Data ordering is not preserved, data may be written into the main file
+        system after its metadata has been committed to the journal.
+
+  commit=nrsec	(*)
+        Ext4 can be told to sync all its data and metadata every 'nrsec'
+        seconds. The default value is 5 seconds.  This means that if you lose
+        your power, you will lose as much as the latest 5 seconds of work (your
+        filesystem will not be damaged though, thanks to the journaling).  This
+        default value (or any low value) will hurt performance, but it's good
+        for data-safety.  Setting it to 0 will have the same effect as leaving
+        it at the default (5 seconds).  Setting it to very large values will
+        improve performance.
+
+  barrier=<0|1(*)>, barrier(*), nobarrier
+        This enables/disables the use of write barriers in the jbd code.
+        barrier=0 disables, barrier=1 enables.  This also requires an IO stack
+        which can support barriers, and if jbd gets an error on a barrier
+        write, it will disable again with a warning.  Write barriers enforce
+        proper on-disk ordering of journal commits, making volatile disk write
+        caches safe to use, at some performance penalty.  If your disks are
+        battery-backed in one way or another, disabling barriers may safely
+        improve performance.  The mount options "barrier" and "nobarrier" can
+        also be used to enable or disable barriers, for consistency with other
+        ext4 mount options.
+
+  inode_readahead_blks=n
+        This tuning parameter controls the maximum number of inode table blocks
+        that ext4's inode table readahead algorithm will pre-read into the
+        buffer cache.  The default value is 32 blocks.
+
+  nouser_xattr
+        Disables Extended User Attributes.  See the attr(5) manual page for
+        more information about extended attributes.
+
+  noacl
+        This option disables POSIX Access Control List support. If ACL support
+        is enabled in the kernel configuration (CONFIG_EXT4_FS_POSIX_ACL), ACL
+        is enabled by default on mount. See the acl(5) manual page for more
+        information about acl.
+
+  bsddf	(*)
+        Make 'df' act like BSD.
+
+  minixdf
+        Make 'df' act like Minix.
+
+  debug
+        Extra debugging information is sent to syslog.
+
+  abort
+        Simulate the effects of calling ext4_abort() for debugging purposes.
+        This is normally used while remounting a filesystem which is already
+        mounted.
+
+  errors=remount-ro
+        Remount the filesystem read-only on an error.
+
+  errors=continue
+        Keep going on a filesystem error.
+
+  errors=panic
+        Panic and halt the machine if an error occurs.  (These mount options
+        override the errors behavior specified in the superblock, which can be
+        configured using tune2fs)
+
+  data_err=ignore(*)
+        Just print an error message if an error occurs in a file data buffer in
+        ordered mode.
+  data_err=abort
+        Abort the journal if an error occurs in a file data buffer in ordered
+        mode.
+
+  grpid | bsdgroups
+        New objects have the group ID of their parent.
+
+  nogrpid (*) | sysvgroups
+        New objects have the group ID of their creator.
+
+  resgid=n
+        The group ID which may use the reserved blocks.
+
+  resuid=n
+        The user ID which may use the reserved blocks.
+
+  sb=
+        Use alternate superblock at this location.
+
+  quota, noquota, grpquota, usrquota
+        These options are ignored by the filesystem. They are used only by
+        quota tools to recognize volumes where quota should be turned on. See
+        documentation in the quota-tools package for more details
+        (http://sourceforge.net/projects/linuxquota).
+
+  jqfmt=<quota type>, usrjquota=<file>, grpjquota=<file>
+        These options tell filesystem details about quota so that quota
+        information can be properly updated during journal replay. They replace
+        the above quota options. See documentation in the quota-tools package
+        for more details (http://sourceforge.net/projects/linuxquota).
+
+  stripe=n
+        Number of filesystem blocks that mballoc will try to use for allocation
+        size and alignment. For RAID5/6 systems this should be the number of
+        data disks *  RAID chunk size in file system blocks.
+
+  delalloc	(*)
+        Defer block allocation until just before ext4 writes out the block(s)
+        in question.  This allows ext4 to better allocation decisions more
+        efficiently.
+
+  nodelalloc
+        Disable delayed allocation.  Blocks are allocated when the data is
+        copied from userspace to the page cache, either via the write(2) system
+        call or when an mmap'ed page which was previously unallocated is
+        written for the first time.
+
+  max_batch_time=usec
+        Maximum amount of time ext4 should wait for additional filesystem
+        operations to be batch together with a synchronous write operation.
+        Since a synchronous write operation is going to force a commit and then
+        a wait for the I/O complete, it doesn't cost much, and can be a huge
+        throughput win, we wait for a small amount of time to see if any other
+        transactions can piggyback on the synchronous write.   The algorithm
+        used is designed to automatically tune for the speed of the disk, by
+        measuring the amount of time (on average) that it takes to finish
+        committing a transaction.  Call this time the "commit time".  If the
+        time that the transaction has been running is less than the commit
+        time, ext4 will try sleeping for the commit time to see if other
+        operations will join the transaction.   The commit time is capped by
+        the max_batch_time, which defaults to 15000us (15ms).   This
+        optimization can be turned off entirely by setting max_batch_time to 0.
+
+  min_batch_time=usec
+        This parameter sets the commit time (as described above) to be at least
+        min_batch_time.  It defaults to zero microseconds.  Increasing this
+        parameter may improve the throughput of multi-threaded, synchronous
+        workloads on very fast disks, at the cost of increasing latency.
+
+  journal_ioprio=prio
+        The I/O priority (from 0 to 7, where 0 is the highest priority) which
+        should be used for I/O operations submitted by kjournald2 during a
+        commit operation.  This defaults to 3, which is a slightly higher
+        priority than the default I/O priority.
+
+  auto_da_alloc(*), noauto_da_alloc
+        Many broken applications don't use fsync() when replacing existing
+        files via patterns such as fd = open("foo.new")/write(fd,..)/close(fd)/
+        rename("foo.new", "foo"), or worse yet, fd = open("foo",
+        O_TRUNC)/write(fd,..)/close(fd).  If auto_da_alloc is enabled, ext4
+        will detect the replace-via-rename and replace-via-truncate patterns
+        and force that any delayed allocation blocks are allocated such that at
+        the next journal commit, in the default data=ordered mode, the data
+        blocks of the new file are forced to disk before the rename() operation
+        is committed.  This provides roughly the same level of guarantees as
+        ext3, and avoids the "zero-length" problem that can happen when a
+        system crashes before the delayed allocation blocks are forced to disk.
+
+  noinit_itable
+        Do not initialize any uninitialized inode table blocks in the
+        background.  This feature may be used by installation CD's so that the
+        install process can complete as quickly as possible; the inode table
+        initialization process would then be deferred until the next time the
+        file system is unmounted.
+
+  init_itable=n
+        The lazy itable init code will wait n times the number of milliseconds
+        it took to zero out the previous block group's inode table.  This
+        minimizes the impact on the system performance while file system's
+        inode table is being initialized.
+
+  discard, nodiscard(*)
+        Controls whether ext4 should issue discard/TRIM commands to the
+        underlying block device when blocks are freed.  This is useful for SSD
+        devices and sparse/thinly-provisioned LUNs, but it is off by default
+        until sufficient testing has been done.
+
+  nouid32
+        Disables 32-bit UIDs and GIDs.  This is for interoperability  with
+        older kernels which only store and expect 16-bit values.
+
+  block_validity(*), noblock_validity
+        These options enable or disable the in-kernel facility for tracking
+        filesystem metadata blocks within internal data structures.  This
+        allows multi- block allocator and other routines to notice bugs or
+        corrupted allocation bitmaps which cause blocks to be allocated which
+        overlap with filesystem metadata blocks.
+
+  dioread_lock, dioread_nolock
+        Controls whether or not ext4 should use the DIO read locking. If the
+        dioread_nolock option is specified ext4 will allocate uninitialized
+        extent before buffer write and convert the extent to initialized after
+        IO completes. This approach allows ext4 code to avoid using inode
+        mutex, which improves scalability on high speed storages. However this
+        does not work with data journaling and dioread_nolock option will be
+        ignored with kernel warning. Note that dioread_nolock code path is only
+        used for extent-based files.  Because of the restrictions this options
+        comprises it is off by default (e.g. dioread_lock).
+
+  max_dir_size_kb=n
+        This limits the size of directories so that any attempt to expand them
+        beyond the specified limit in kilobytes will cause an ENOSPC error.
+        This is useful in memory constrained environments, where a very large
+        directory can cause severe performance problems or even provoke the Out
+        Of Memory killer.  (For example, if there is only 512mb memory
+        available, a 176mb directory may seriously cramp the system's style.)
+
+  i_version
+        Enable 64-bit inode version support. This option is off by default.
+
+  dax
+        Use direct access (no page cache).  See
+        Documentation/filesystems/dax.txt.  Note that this option is
+        incompatible with data=journal.
+
+Data Mode
+=========
+There are 3 different data modes:
+
+* writeback mode
+
+  In data=writeback mode, ext4 does not journal data at all.  This mode provides
+  a similar level of journaling as that of XFS, JFS, and ReiserFS in its default
+  mode - metadata journaling.  A crash+recovery can cause incorrect data to
+  appear in files which were written shortly before the crash.  This mode will
+  typically provide the best ext4 performance.
+
+* ordered mode
+
+  In data=ordered mode, ext4 only officially journals metadata, but it logically
+  groups metadata information related to data changes with the data blocks into
+  a single unit called a transaction.  When it's time to write the new metadata
+  out to disk, the associated data blocks are written first.  In general, this
+  mode performs slightly slower than writeback but significantly faster than
+  journal mode.
+
+* journal mode
+
+  data=journal mode provides full data and metadata journaling.  All new data is
+  written to the journal first, and then to its final location.  In the event of
+  a crash, the journal can be replayed, bringing both data and metadata into a
+  consistent state.  This mode is the slowest except when data needs to be read
+  from and written to disk at the same time where it outperforms all others
+  modes.  Enabling this mode will disable delayed allocation and O_DIRECT
+  support.

+
+  mb_stream_req
+        Files which have fewer blocks than this tunable parameter will have

+        This is RW file and contains number of reserved clusters in the file
+        system which will be used in the specific situations to avoid costly
+        zeroout, unexpected ENOSPC, or possible data loss. The default is 2% or
+        4096 clusters, whichever is smaller and this can be changed however it
+        can never exceed number of clusters in the file system. If there is not
+        enough space for the reserved space when mounting the file mount will
+        _not_ fail.
+
+Ioctls
+======
+
+There is some Ext4 specific functionality which can be accessed by applications
+through the system call interfaces. The list of all Ext4 specific ioctls are
+shown in the table below.
+
+Table of Ext4 specific ioctls
+
+  EXT4_IOC_GETFLAGS
+        Get additional attributes associated with inode.  The ioctl argument is
+        an integer bitfield, with bit values described in ext4.h. This ioctl is
+        an alias for FS_IOC_GETFLAGS.
+
+  EXT4_IOC_SETFLAGS
+        Set additional attributes associated with inode.  The ioctl argument is
+        an integer bitfield, with bit values described in ext4.h. This ioctl is
+        an alias for FS_IOC_SETFLAGS.
+
+  EXT4_IOC_GETVERSION, EXT4_IOC_GETVERSION_OLD
+        Get the inode i_generation number stored for each inode. The
+        i_generation number is normally changed only when new inode is created
+        and it is particularly useful for network filesystems. The '_OLD'
+        version of this ioctl is an alias for FS_IOC_GETVERSION.
+
+  EXT4_IOC_SETVERSION, EXT4_IOC_SETVERSION_OLD
+        Set the inode i_generation number stored for each inode. The '_OLD'
+        version of this ioctl is an alias for FS_IOC_SETVERSION.
+
+  EXT4_IOC_GROUP_EXTEND
+        This ioctl has the same purpose as the resize mount option. It allows
+        to resize filesystem to the end of the last existing block group,
+        further resize has to be done with resize2fs, either online, or
+        offline. The argument points to the unsigned logn number representing
+        the filesystem new block count.
+
+  EXT4_IOC_MOVE_EXT
+        Move the block extents from orig_fd (the one this ioctl is pointing to)
+        to the donor_fd (the one specified in move_extent structure passed as
+        an argument to this ioctl). Then, exchange inode metadata between
+        orig_fd and donor_fd.  This is especially useful for online
+        defragmentation, because the allocator has the opportunity to allocate
+        moved blocks better, ideally into one contiguous extent.
+
+  EXT4_IOC_GROUP_ADD
+        Add a new group descriptor to an existing or new group descriptor
+        block. The new group descriptor is described by ext4_new_group_input
+        structure, which is passed as an argument to this ioctl. This is
+        especially useful in conjunction with EXT4_IOC_GROUP_EXTEND, which
+        allows online resize of the filesystem to the end of the last existing
+        block group.  Those two ioctls combined is used in userspace online
+        resize tool (e.g. resize2fs).
+
+  EXT4_IOC_MIGRATE
+        This ioctl operates on the filesystem itself.  It converts (migrates)
+        ext3 indirect block mapped inode to ext4 extent mapped inode by walking
+        through indirect block mapping of the original inode and converting
+        contiguous block ranges into ext4 extents of the temporary inode. Then,
+        inodes are swapped. This ioctl might help, when migrating from ext3 to
+        ext4 filesystem, however suggestion is to create fresh ext4 filesystem
+        and copy data from the backup. Note, that filesystem has to support
+        extents for this ioctl to work.
+
+  EXT4_IOC_ALLOC_DA_BLKS
+        Force all of the delay allocated blocks to be allocated to preserve
+        application-expected ext3 behaviour. Note that this will also start
+        triggering a write of the data blocks, but this behaviour may change in
+        the future as it is not necessary and has been done this way only for
+        sake of simplicity.
+
+  EXT4_IOC_RESIZE_FS
+        Resize the filesystem to a new size.  The number of blocks of resized
+        filesystem is passed in via 64 bit integer argument.  The kernel
+        allocates bitmaps and inode table, the userspace tool thus just passes
+        the new number of blocks.
+
+  EXT4_IOC_SWAP_BOOT
+        Swap i_blocks and associated attributes (like i_blocks, i_size,
+        i_flags, ...) from the specified inode with inode EXT4_BOOT_LOADER_INO
+        (#5). This is typically used to store a boot loader in a secure part of
+        the filesystem, where it can't be changed by a normal user by accident.
+        The data blocks of the previous boot loader will be associated with the
+        given inode.

-Memory hotplug event notifier
-=============================
-
-Hotplugging events are sent to a notification queue.
-
-There are six types of notification defined in include/linux/memory.h:
-
-MEM_GOING_ONLINE
-  Generated before new memory becomes available in order to be able to
-  prepare subsystems to handle memory. The page allocator is still unable
-  to allocate from the new memory.
-
-MEM_CANCEL_ONLINE
-  Generated if MEMORY_GOING_ONLINE fails.
-
-MEM_ONLINE
-  Generated when memory has successfully brought online. The callback may
-  allocate pages from the new memory.
-
-MEM_GOING_OFFLINE
-  Generated to begin the process of offlining memory. Allocations are no
-  longer possible from the memory but some of the memory to be offlined
-  is still in use. The callback can be used to free memory known to a
-  subsystem from the indicated memory block.
-
-MEM_CANCEL_OFFLINE
-  Generated if MEMORY_GOING_OFFLINE fails. Memory is available again from
-  the memory block that we attempted to offline.
-
-MEM_OFFLINE
-  Generated after offlining memory is complete.
-
-A callback routine can be registered by calling::
-
-  hotplug_memory_notifier(callback_func, priority)
-
-Callback functions with higher values of priority are called before callback
-functions with lower values.
-
-A callback function must have the following prototype::
-
-  int callback_func(
-    struct notifier_block *self, unsigned long action, void *arg);
-
-The first argument of the callback function (self) is a pointer to the block
-of the notifier chain that points to the callback function itself.
-The second argument (action) is one of the event types described above.
-The third argument (arg) passes a pointer of struct memory_notify::
-
-	struct memory_notify {
-		unsigned long start_pfn;
-		unsigned long nr_pages;
-		int status_change_nid_normal;
-		int status_change_nid_high;
-		int status_change_nid;
-	}
-
-- start_pfn is start_pfn of online/offline memory.
-- nr_pages is # of pages of online/offline memory.
-- status_change_nid_normal is set node id when N_NORMAL_MEMORY of nodemask
-  is (will be) set/clear, if this is -1, then nodemask status is not changed.
-- status_change_nid_high is set node id when N_HIGH_MEMORY of nodemask
-  is (will be) set/clear, if this is -1, then nodemask status is not changed.
-- status_change_nid is set node id when N_MEMORY of nodemask is (will be)
-  set/clear. It means a new(memoryless) node gets new memory by online and a
-  node loses all memory. If this is -1, then nodemask status is not changed.
-
-  If status_changed_nid* >= 0, callback should create/discard structures for the
-  node if necessary.
-
-The callback routine shall return one of the values
-NOTIFY_DONE, NOTIFY_OK, NOTIFY_BAD, NOTIFY_STOP
-defined in include/linux/notifier.h
-
-NOTIFY_DONE and NOTIFY_OK have no effect on the further processing.
-
-NOTIFY_BAD is used as response to the MEM_GOING_ONLINE, MEM_GOING_OFFLINE,
-MEM_ONLINE, or MEM_OFFLINE action to cancel hotplugging. It stops
-further processing of the notification queue.
-
-NOTIFY_STOP stops further processing of the notification queue.

+HugeTLBpage on ARM64
+====================
+
+Hugepage relies on making efficient use of TLBs to improve performance of
+address translations. The benefit depends on both -
+
+  - the size of hugepages
+  - size of entries supported by the TLBs
+
+The ARM64 port supports two flavours of hugepages.
+
+1) Block mappings at the pud/pmd level
+--------------------------------------
+
+These are regular hugepages where a pmd or a pud page table entry points to a
+block of memory. Regardless of the supported size of entries in TLB, block
+mappings reduce the depth of page table walk needed to translate hugepage
+addresses.
+
+2) Using the Contiguous bit
+---------------------------
+
+The architecture provides a contiguous bit in the translation table entries
+(D4.5.3, ARM DDI 0487C.a) that hints to the MMU to indicate that it is one of a
+contiguous set of entries that can be cached in a single TLB entry.
+
+The contiguous bit is used in Linux to increase the mapping size at the pmd and
+pte (last) level. The number of supported contiguous entries varies by page size
+and level of the page table.
+
+
+The following hugepage sizes are supported -
+
+         CONT PTE    PMD    CONT PMD    PUD
+         --------    ---    --------    ---

-				 INTRODUCTION
-
-Mylex, Inc. designs and manufactures a variety of high performance PCI RAID
-controllers.  Mylex Corporation is located at 34551 Ardenwood Blvd., Fremont,
-California 94555, USA and can be reached at 510.796.6100 or on the World Wide
-Web at http://www.mylex.com.  Mylex Technical Support can be reached by
-electronic mail at mylexsup@us.ibm.com, by voice at 510.608.2400, or by FAX at
-510.745.7715.  Contact information for offices in Europe and Japan is available
-on their Web site.
-
-The latest information on Linux support for DAC960 PCI RAID Controllers, as
-well as the most recent release of this driver, will always be available from
-my Linux Home Page at URL "http://www.dandelion.com/Linux/".  The Linux DAC960
-driver supports all current Mylex PCI RAID controllers including the new
-eXtremeRAID 2000/3000 and AcceleRAID 352/170/160 models which have an entirely
-new firmware interface from the older eXtremeRAID 1100, AcceleRAID 150/200/250,
-and DAC960PJ/PG/PU/PD/PL.  See below for a complete controller list as well as
-minimum firmware version requirements.  For simplicity, in most places this
-documentation refers to DAC960 generically rather than explicitly listing all
-the supported models.
-
-Driver bug reports should be sent via electronic mail to "lnz@dandelion.com".
-Please include with the bug report the complete configuration messages reported
-by the driver at startup, along with any subsequent system messages relevant to
-the controller's operation, and a detailed description of your system's
-hardware configuration.  Driver bugs are actually quite rare; if you encounter
-problems with disks being marked offline, for example, please contact Mylex
-Technical Support as the problem is related to the hardware configuration
-rather than the Linux driver.
-
-Please consult the RAID controller documentation for detailed information
-regarding installation and configuration of the controllers.  This document
-primarily provides information specific to the Linux support.
-
-
-				DRIVER FEATURES
-
-The DAC960 RAID controllers are supported solely as high performance RAID
-controllers, not as interfaces to arbitrary SCSI devices.  The Linux DAC960
-driver operates at the block device level, the same level as the SCSI and IDE
-drivers.  Unlike other RAID controllers currently supported on Linux, the
-DAC960 driver is not dependent on the SCSI subsystem, and hence avoids all the
-complexity and unnecessary code that would be associated with an implementation
-as a SCSI driver.  The DAC960 driver is designed for as high a performance as
-possible with no compromises or extra code for compatibility with lower
-performance devices.  The DAC960 driver includes extensive error logging and
-online configuration management capabilities.  Except for initial configuration
-of the controller and adding new disk drives, most everything can be handled
-from Linux while the system is operational.
-
-The DAC960 driver is architected to support up to 8 controllers per system.
-Each DAC960 parallel SCSI controller can support up to 15 disk drives per
-channel, for a maximum of 60 drives on a four channel controller; the fibre
-channel eXtremeRAID 3000 controller supports up to 125 disk drives per loop for
-a total of 250 drives.  The drives installed on a controller are divided into
-one or more "Drive Groups", and then each Drive Group is subdivided further
-into 1 to 32 "Logical Drives".  Each Logical Drive has a specific RAID Level
-and caching policy associated with it, and it appears to Linux as a single
-block device.  Logical Drives are further subdivided into up to 7 partitions
-through the normal Linux and PC disk partitioning schemes.  Logical Drives are
-also known as "System Drives", and Drive Groups are also called "Packs".  Both
-terms are in use in the Mylex documentation; I have chosen to standardize on
-the more generic "Logical Drive" and "Drive Group".
-
-DAC960 RAID disk devices are named in the style of the obsolete Device File
-System (DEVFS).  The device corresponding to Logical Drive D on Controller C
-is referred to as /dev/rd/cCdD, and the partitions are called /dev/rd/cCdDp1
-through /dev/rd/cCdDp7.  For example, partition 3 of Logical Drive 5 on
-Controller 2 is referred to as /dev/rd/c2d5p3.  Note that unlike with SCSI
-disks the device names will not change in the event of a disk drive failure.
-The DAC960 driver is assigned major numbers 48 - 55 with one major number per
-controller.  The 8 bits of minor number are divided into 5 bits for the Logical
-Drive and 3 bits for the partition.

-			      DRIVER INSTALLATION
-
-This distribution was prepared for Linux kernel version 2.2.19 or 2.4.12.
-
-To install the DAC960 RAID driver, you may use the following commands,
-replacing "/usr/src" with wherever you keep your Linux kernel source tree:
-
-  cd /usr/src
-  tar -xvzf DAC960-2.2.11.tar.gz (or DAC960-2.4.11.tar.gz)
-  mv README.DAC960 linux/Documentation
-  mv DAC960.[ch] linux/drivers/block
-  patch -p0 < DAC960.patch (if DAC960.patch is included)
-  cd linux
-  make config
-  make bzImage (or zImage)
-
-Then install "arch/x86/boot/bzImage" or "arch/x86/boot/zImage" as your
-standard kernel, run lilo if appropriate, and reboot.
-
-To create the necessary devices in /dev, the "make_rd" script included in
-"DAC960-Utilities.tar.gz" from http://www.dandelion.com/Linux/ may be used.
-LILO 21 and FDISK v2.9 include DAC960 support; also included in this archive
-are patches to LILO 20 and FDISK v2.8 that add DAC960 support, along with
-statically linked executables of LILO and FDISK.  This modified version of LILO
-will allow booting from a DAC960 controller and/or mounting the root file
-system from a DAC960.
-
-Red Hat Linux 6.0 and SuSE Linux 6.1 include support for Mylex PCI RAID
-controllers.  Installing directly onto a DAC960 may be problematic from other
-Linux distributions until their installation utilities are updated.
-
-
-			      INSTALLATION NOTES
-
-Before installing Linux or adding DAC960 logical drives to an existing Linux
-system, the controller must first be configured to provide one or more logical
-drives using the BIOS Configuration Utility or DACCF.  Please note that since
-there are only at most 6 usable partitions on each logical drive, systems
-requiring more partitions should subdivide a drive group into multiple logical
-drives, each of which can have up to 6 usable partitions.  Also, note that with
-large disk arrays it is advisable to enable the 8GB BIOS Geometry (255/63)
-rather than accepting the default 2GB BIOS Geometry (128/32); failing to so do
-will cause the logical drive geometry to have more than 65535 cylinders which
-will make it impossible for FDISK to be used properly.  The 8GB BIOS Geometry
-can be enabled by configuring the DAC960 BIOS, which is accessible via Alt-M
-during the BIOS initialization sequence.
-
-For maximum performance and the most efficient E2FSCK performance, it is
-recommended that EXT2 file systems be built with a 4KB block size and 16 block
-stride to match the DAC960 controller's 64KB default stripe size.  The command
-"mke2fs -b 4096 -R stride=16 <device>" is appropriate.  Unless there will be a
-large number of small files on the file systems, it is also beneficial to add
-the "-i 16384" option to increase the bytes per inode parameter thereby
-reducing the file system metadata.  Finally, on systems that will only be run
-with Linux 2.2 or later kernels it is beneficial to enable sparse superblocks
-with the "-s 1" option.

-
-		CONTROLLER CONFIGURATION AND STATUS MONITORING
-
-The DAC960 RAID controllers running firmware 4.06 or above include a Background
-Initialization facility so that system downtime is minimized both for initial
-installation and subsequent configuration of additional storage.  The BIOS
-Configuration Utility (accessible via Alt-R during the BIOS initialization
-sequence) is used to quickly configure the controller, and then the logical
-drives that have been created are available for immediate use even while they
-are still being initialized by the controller.  The primary need for online
-configuration and status monitoring is then to avoid system downtime when disk
-drives fail and must be replaced.  Mylex's online monitoring and configuration
-utilities are being ported to Linux and will become available at some point in
-the future.  Note that with a SAF-TE (SCSI Accessed Fault-Tolerant Enclosure)
-enclosure, the controller is able to rebuild failed drives automatically as
-soon as a drive replacement is made available.
-
-The primary interfaces for controller configuration and status monitoring are
-special files created in the /proc/rd/... hierarchy along with the normal
-system console logging mechanism.  Whenever the system is operating, the DAC960
-driver queries each controller for status information every 10 seconds, and
-checks for additional conditions every 60 seconds.  The initial status of each
-controller is always available for controller N in /proc/rd/cN/initial_status,
-and the current status as of the last status monitoring query is available in
-/proc/rd/cN/current_status.  In addition, status changes are also logged by the
-driver to the system console and will appear in the log files maintained by
-syslog.  The progress of asynchronous rebuild or consistency check operations
-is also available in /proc/rd/cN/current_status, and progress messages are
-logged to the system console at most every 60 seconds.
-
-Starting with the 2.2.3/2.0.3 versions of the driver, the status information
-available in /proc/rd/cN/initial_status and /proc/rd/cN/current_status has been
-augmented to include the vendor, model, revision, and serial number (if
-available) for each physical device found connected to the controller:

-To simplify the monitoring process for custom software, the special file
-/proc/rd/status returns "OK" when all DAC960 controllers in the system are
-operating normally and no failures have occurred, or "ALERT" if any logical
-drives are offline or critical or any non-standby physical drives are dead.
-
-Configuration commands for controller N are available via the special file
-/proc/rd/cN/user_command.  A human readable command can be written to this
-special file to initiate a configuration operation, and the results of the
-operation can then be read back from the special file in addition to being
-logged to the system console.  The shell command sequence
-
-  echo "<configuration-command>" > /proc/rd/c0/user_command
-  cat /proc/rd/c0/user_command
-
-is typically used to execute configuration commands.  The configuration
-commands are:
-
-  flush-cache
-
-    The "flush-cache" command flushes the controller's cache.  The system
-    automatically flushes the cache at shutdown or if the driver module is
-    unloaded, so this command is only needed to be certain a write back cache
-    is flushed to disk before the system is powered off by a command to a UPS.
-    Note that the flush-cache command also stops an asynchronous rebuild or
-    consistency check, so it should not be used except when the system is being
-    halted.
-
-  kill <channel>:<target-id>
-
-    The "kill" command marks the physical drive <channel>:<target-id> as DEAD.
-    This command is provided primarily for testing, and should not be used
-    during normal system operation.
-
-  make-online <channel>:<target-id>
-
-    The "make-online" command changes the physical drive <channel>:<target-id>
-    from status DEAD to status ONLINE.  In cases where multiple physical drives
-    have been killed simultaneously, this command may be used to bring all but
-    one of them back online, after which a rebuild to the final drive is
-    necessary.
-
-    Warning: make-online should only be used on a dead physical drive that is
-    an active part of a drive group, never on a standby drive.  The command
-    should never be used on a dead drive that is part of a critical logical
-    drive; rebuild should be used if only a single drive is dead.
-
-  make-standby <channel>:<target-id>
-
-    The "make-standby" command changes physical drive <channel>:<target-id>
-    from status DEAD to status STANDBY.  It should only be used in cases where
-    a dead drive was replaced after an automatic rebuild was performed onto a
-    standby drive.  It cannot be used to add a standby drive to the controller
-    configuration if one was not created initially; the BIOS Configuration
-    Utility must be used for that currently.
-
-  rebuild <channel>:<target-id>
-
-    The "rebuild" command initiates an asynchronous rebuild onto physical drive
-    <channel>:<target-id>.  It should only be used when a dead drive has been
-    replaced.
-
-  check-consistency <logical-drive-number>
-
-    The "check-consistency" command initiates an asynchronous consistency check
-    of <logical-drive-number> with automatic restoration.  It can be used
-    whenever it is desired to verify the consistency of the redundancy
-    information.
-
-  cancel-rebuild
-  cancel-consistency-check
-
-    The "cancel-rebuild" and "cancel-consistency-check" commands cancel any
-    rebuild or consistency check operations previously initiated.
-

-	       EXAMPLE I - DRIVE FAILURE WITHOUT A STANDBY DRIVE
-
-The following annotated logs demonstrate the controller configuration and and
-online status monitoring capabilities of the Linux DAC960 Driver.  The test
-configuration comprises 6 1GB Quantum Atlas I disk drives on two channels of a
-DAC960PJ controller.  The physical drives are configured into a single drive
-group without a standby drive, and the drive group has been configured into two
-logical drives, one RAID-5 and one RAID-6.  Note that these logs are from an
-earlier version of the driver and the messages have changed somewhat with newer
-releases, but the functionality remains similar.  First, here is the current
-status of the RAID configuration:

-
-gwynedd:/u/lnz# cat /proc/rd/status
-OK
-
-The above messages indicate that everything is healthy, and /proc/rd/status
-returns "OK" indicating that there are no problems with any DAC960 controller
-in the system.  For demonstration purposes, while I/O is active Physical Drive
-1:1 is now disconnected, simulating a drive failure.  The failure is noted by
-the driver within 10 seconds of the controller's having detected it, and the
-driver logs the following console status messages indicating that Logical
-Drives 0 and 1 are now CRITICAL as a result of Physical Drive 1:1 being DEAD:
-
-DAC960#0: Physical Drive 1:2 Error Log: Sense Key = 6, ASC = 29, ASCQ = 02
-DAC960#0: Physical Drive 1:3 Error Log: Sense Key = 6, ASC = 29, ASCQ = 02

-DAC960#0: Logical Drive 0 (/dev/rd/c0d0) is now CRITICAL
-DAC960#0: Logical Drive 1 (/dev/rd/c0d1) is now CRITICAL
-
-The Sense Keys logged here are just Check Condition / Unit Attention conditions
-arising from a SCSI bus reset that is forced by the controller during its error
-recovery procedures.  Concurrently with the above, the driver status available
-from /proc/rd also reflects the drive failure.  The status message in
-/proc/rd/status has changed from "OK" to "ALERT":
-
-gwynedd:/u/lnz# cat /proc/rd/status
-ALERT
-
-and /proc/rd/c0/current_status has been updated:

-    /dev/rd/c0d1: RAID-6, Critical, 3305472 blocks, Write Thru
-  No Rebuild or Consistency Check in Progress
-
-Since there are no standby drives configured, the system can continue to access
-the logical drives in a performance degraded mode until the failed drive is
-replaced and a rebuild operation completed to restore the redundancy of the
-logical drives.  Once Physical Drive 1:1 is replaced with a properly
-functioning drive, or if the physical drive was killed without having failed
-(e.g., due to electrical problems on the SCSI bus), the user can instruct the
-controller to initiate a rebuild operation onto the newly replaced drive:
-
-gwynedd:/u/lnz# echo "rebuild 1:1" > /proc/rd/c0/user_command
-gwynedd:/u/lnz# cat /proc/rd/c0/user_command
-Rebuild of Physical Drive 1:1 Initiated
-
-The echo command instructs the controller to initiate an asynchronous rebuild
-operation onto Physical Drive 1:1, and the status message that results from the
-operation is then available for reading from /proc/rd/c0/user_command, as well
-as being logged to the console by the driver.
-
-Within 10 seconds of this command the driver logs the initiation of the
-asynchronous rebuild operation:
-
-DAC960#0: Rebuild of Physical Drive 1:1 Initiated
-DAC960#0: Physical Drive 1:1 Error Log: Sense Key = 6, ASC = 29, ASCQ = 01

+=======================
+Memory Allocation Guide
+=======================
+
+Linux provides a variety of APIs for memory allocation. You can
+allocate small chunks using `kmalloc` or `kmem_cache_alloc` families,
+large virtually contiguous areas using `vmalloc` and its derivatives,
+or you can directly request pages from the page allocator with
+`alloc_pages`. It is also possible to use more specialized allocators,
+for instance `cma_alloc` or `zs_malloc`.
+
+Most of the memory allocation APIs use GFP flags to express how that
+memory should be allocated. The GFP acronym stands for "get free
+pages", the underlying memory allocation function.
+
+Diversity of the allocation APIs combined with the numerous GFP flags
+makes the question "How should I allocate memory?" not that easy to
+answer, although very likely you should use
+
+::
+
+  kzalloc(<size>, GFP_KERNEL);
+
+Of course there are cases when other allocation APIs and different GFP
+flags must be used.
+
+Get Free Page flags
+===================
+
+The GFP flags control the allocators behavior. They tell what memory
+zones can be used, how hard the allocator should try to find free
+memory, whether the memory can be accessed by the userspace etc. The
+:ref:`Documentation/core-api/mm-api.rst <mm-api-gfp-flags>` provides
+reference documentation for the GFP flags and their combinations and
+here we briefly outline their recommended usage:
+
+  * Most of the time ``GFP_KERNEL`` is what you need. Memory for the
+    kernel data structures, DMAable memory, inode cache, all these and
+    many other allocations types can use ``GFP_KERNEL``. Note, that
+    using ``GFP_KERNEL`` implies ``GFP_RECLAIM``, which means that
+    direct reclaim may be triggered under memory pressure; the calling
+    context must be allowed to sleep.
+  * If the allocation is performed from an atomic context, e.g interrupt
+    handler, use ``GFP_NOWAIT``. This flag prevents direct reclaim and
+    IO or filesystem operations. Consequently, under memory pressure
+    ``GFP_NOWAIT`` allocation is likely to fail. Allocations which
+    have a reasonable fallback should be using ``GFP_NOWARN``.
+  * If you think that accessing memory reserves is justified and the kernel
+    will be stressed unless allocation succeeds, you may use ``GFP_ATOMIC``.
+  * Untrusted allocations triggered from userspace should be a subject
+    of kmem accounting and must have ``__GFP_ACCOUNT`` bit set. There
+    is the handy ``GFP_KERNEL_ACCOUNT`` shortcut for ``GFP_KERNEL``
+    allocations that should be accounted.
+  * Userspace allocations should use either of the ``GFP_USER``,
+    ``GFP_HIGHUSER`` or ``GFP_HIGHUSER_MOVABLE`` flags. The longer
+    the flag name the less restrictive it is.
+
+    ``GFP_HIGHUSER_MOVABLE`` does not require that allocated memory
+    will be directly accessible by the kernel and implies that the
+    data is movable.
+
+    ``GFP_HIGHUSER`` means that the allocated memory is not movable,
+    but it is not required to be directly accessible by the kernel. An
+    example may be a hardware allocation that maps data directly into
+    userspace but has no addressing limitations.
+
+    ``GFP_USER`` means that the allocated memory is not movable and it
+    must be directly accessible by the kernel.
+
+You may notice that quite a few allocations in the existing code
+specify ``GFP_NOIO`` or ``GFP_NOFS``. Historically, they were used to
+prevent recursion deadlocks caused by direct memory reclaim calling
+back into the FS or IO paths and blocking on already held
+resources. Since 4.12 the preferred way to address this issue is to
+use new scope APIs described in
+:ref:`Documentation/core-api/gfp_mask-from-fs-io.rst <gfp_mask_from_fs_io>`.
+
+Other legacy GFP flags are ``GFP_DMA`` and ``GFP_DMA32``. They are
+used to ensure that the allocated memory is accessible by hardware
+with limited addressing capabilities. So unless you are writing a
+driver for a device with such restrictions, avoid using these flags.
+And even with hardware with restrictions it is preferable to use
+`dma_alloc*` APIs.
+
+Selecting memory allocator
+==========================
+
+The most straightforward way to allocate memory is to use a function
+from the :c:func:`kmalloc` family. And, to be on the safe size it's
+best to use routines that set memory to zero, like
+:c:func:`kzalloc`. If you need to allocate memory for an array, there
+are :c:func:`kmalloc_array` and :c:func:`kcalloc` helpers.
+
+The maximal size of a chunk that can be allocated with `kmalloc` is
+limited. The actual limit depends on the hardware and the kernel
+configuration, but it is a good practice to use `kmalloc` for objects
+smaller than page size.
+
+For large allocations you can use :c:func:`vmalloc` and
+:c:func:`vzalloc`, or directly request pages from the page
+allocator. The memory allocated by `vmalloc` and related functions is
+not physically contiguous.
+
+If you are not sure whether the allocation size is too large for
+`kmalloc`, it is possible to use :c:func:`kvmalloc` and its
+derivatives. It will try to allocate memory with `kmalloc` and if the
+allocation fails it will be retried with `vmalloc`. There are
+restrictions on which GFP flags can be used with `kvmalloc`; please
+see :c:func:`kvmalloc_node` reference documentation. Note that
+`kvmalloc` may return memory that is not physically contiguous.
+
+If you need to allocate many identical objects you can use the slab
+cache allocator. The cache should be set up with
+:c:func:`kmem_cache_create` before it can be used. Afterwards
+:c:func:`kmem_cache_alloc` and its convenience wrappers can allocate
+memory from that cache.
+
+When the allocated memory is no longer needed it must be freed. You
+can use :c:func:`kvfree` for the memory allocated with `kmalloc`,
+`vmalloc` and `kvmalloc`. The slab caches should be freed with
+:c:func:`kmem_cache_free`. And don't forget to destroy the cache with
+:c:func:`kmem_cache_destroy`.

+Memory hotplug event notifier
+=============================
+
+Hotplugging events are sent to a notification queue.
+
+There are six types of notification defined in ``include/linux/memory.h``:
+
+MEM_GOING_ONLINE
+  Generated before new memory becomes available in order to be able to
+  prepare subsystems to handle memory. The page allocator is still unable
+  to allocate from the new memory.
+
+MEM_CANCEL_ONLINE
+  Generated if MEM_GOING_ONLINE fails.
+
+MEM_ONLINE
+  Generated when memory has successfully brought online. The callback may
+  allocate pages from the new memory.
+
+MEM_GOING_OFFLINE
+  Generated to begin the process of offlining memory. Allocations are no
+  longer possible from the memory but some of the memory to be offlined
+  is still in use. The callback can be used to free memory known to a
+  subsystem from the indicated memory block.
+
+MEM_CANCEL_OFFLINE
+  Generated if MEM_GOING_OFFLINE fails. Memory is available again from
+  the memory block that we attempted to offline.
+
+MEM_OFFLINE
+  Generated after offlining memory is complete.
+
+A callback routine can be registered by calling::
+
+  hotplug_memory_notifier(callback_func, priority)
+
+Callback functions with higher values of priority are called before callback
+functions with lower values.
+
+A callback function must have the following prototype::
+
+  int callback_func(
+    struct notifier_block *self, unsigned long action, void *arg);
+
+The first argument of the callback function (self) is a pointer to the block
+of the notifier chain that points to the callback function itself.
+The second argument (action) is one of the event types described above.
+The third argument (arg) passes a pointer of struct memory_notify::
+
+	struct memory_notify {
+		unsigned long start_pfn;
+		unsigned long nr_pages;
+		int status_change_nid_normal;
+		int status_change_nid_high;
+		int status_change_nid;
+	}
+
+- start_pfn is start_pfn of online/offline memory.
+- nr_pages is # of pages of online/offline memory.
+- status_change_nid_normal is set node id when N_NORMAL_MEMORY of nodemask
+  is (will be) set/clear, if this is -1, then nodemask status is not changed.
+- status_change_nid_high is set node id when N_HIGH_MEMORY of nodemask
+  is (will be) set/clear, if this is -1, then nodemask status is not changed.
+- status_change_nid is set node id when N_MEMORY of nodemask is (will be)
+  set/clear. It means a new(memoryless) node gets new memory by online and a
+  node loses all memory. If this is -1, then nodemask status is not changed.
+
+  If status_changed_nid* >= 0, callback should create/discard structures for the
+  node if necessary.
+
+The callback routine shall return one of the values
+NOTIFY_DONE, NOTIFY_OK, NOTIFY_BAD, NOTIFY_STOP
+defined in ``include/linux/notifier.h``
+
+NOTIFY_DONE and NOTIFY_OK have no effect on the further processing.
+
+NOTIFY_BAD is used as response to the MEM_GOING_ONLINE, MEM_GOING_OFFLINE,
+MEM_ONLINE, or MEM_OFFLINE action to cancel hotplugging. It stops
+further processing of the notification queue.
+
+NOTIFY_STOP stops further processing of the notification queue.
+
+Locking Internals
+=================
+
+When adding/removing memory that uses memory block devices (i.e. ordinary RAM),
+the device_hotplug_lock should be held to:
+
+- synchronize against online/offline requests (e.g. via sysfs). This way, memory
+  block devices can only be accessed (.online/.state attributes) by user
+  space once memory has been fully added. And when removing memory, we
+  know nobody is in critical sections.
+- synchronize against CPU hotplug and similar (e.g. relevant for ACPI and PPC)
+
+Especially, there is a possible lock inversion that is avoided using
+device_hotplug_lock when adding memory and user space tries to online that
+memory faster than expected:
+
+- device_online() will first take the device_lock(), followed by
+  mem_hotplug_lock
+- add_memory_resource() will first take the mem_hotplug_lock, followed by
+  the device_lock() (while creating the devices, during bus_add_device()).
+
+As the device is visible to user space before taking the device_lock(), this
+can result in a lock inversion.
+
+onlining/offlining of memory should be done via device_online()/
+device_offline() - to make sure it is properly synchronized to actions
+via sysfs. Holding device_hotplug_lock is advised (to e.g. protect online_type)
+
+When adding/removing/onlining/offlining memory or adding/removing
+heterogeneous/device memory, we should always hold the mem_hotplug_lock in
+write mode to serialise memory hotplug (e.g. access to global/zone
+variables).
+
+In addition, mem_hotplug_lock (in contrast to device_hotplug_lock) in read
+mode allows for a quite efficient get_online_mems/put_online_mems
+implementation, so code accessing memory can protect from that memory
+vanishing.

+Marvell SEI (System Error Interrupt) Controller
+-----------------------------------------------
+
+Marvell SEI (System Error Interrupt) controller is an interrupt
+aggregator. It receives interrupts from several sources and aggregates
+them to a single interrupt line (an SPI) on the parent interrupt
+controller.
+
+This interrupt controller can handle up to 64 SEIs, a set comes from the
+AP and is wired while a second set comes from the CPs by the mean of
+MSIs.
+
+Required properties:
+
+- compatible: should be one of:
+              * "marvell,ap806-sei"
+- reg: SEI registers location and length.
+- interrupts: identifies the parent IRQ that will be triggered.
+- #interrupt-cells: number of cells to define an SEI wired interrupt
+                    coming from the AP, should be 1. The cell is the IRQ
+                    number.
+- interrupt-controller: identifies the node as an interrupt controller
+                        for AP interrupts.
+- msi-controller: identifies the node as an MSI controller for the CPs
+                  interrupts.

+Microsemi Ocelot SerDes muxing driver
+-------------------------------------
+
+On Microsemi Ocelot, there is a handful of registers in HSIO address
+space for setting up the SerDes to switch port muxing.
+
+A SerDes X can be "muxed" to work with switch port Y or Z for example.
+One specific SerDes can also be used as a PCIe interface.
+
+Hence, a SerDes represents an interface, be it an Ethernet or a PCIe one.
+
+There are two kinds of SerDes: SERDES1G supports 10/100Mbps in
+half/full-duplex and 1000Mbps in full-duplex mode while SERDES6G supports
+10/100Mbps in half/full-duplex and 1000/2500Mbps in full-duplex mode.
+
+Also, SERDES6G number (aka "macro") 0 is the only interface supporting
+QSGMII.
+
+This is a child of the HSIO syscon ("mscc,ocelot-hsio", see
+Documentation/devicetree/bindings/mips/mscc.txt) on the Microsemi Ocelot.
+
+Required properties:
+
+- compatible: should be "mscc,vsc7514-serdes"
+- #phy-cells : from the generic phy bindings, must be 2.
+	       The first number defines the input port to use for a given
+	       SerDes macro. The second defines the macro to use. They are
+	       defined in dt-bindings/phy/phy-ocelot-serdes.h
+
+Example:
+
+	serdes: serdes {
+		compatible = "mscc,vsc7514-serdes";
+		#phy-cells = <2>;
+	};
+
+	ethernet {
+		port1 {
+			phy-handle = <&phy_foo>;
+			/* Link SERDES1G_5 to port1 */
+			phys = <&serdes 1 SERDES1G_5>;
+		};
+	};

+Broadcom Northstar pins mux controller
+
+Some of Northstar SoCs's pins can be used for various purposes thanks to the mux
+controller. This binding allows describing mux controller and listing available

+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+The pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as pull-up, drive strength, etc.
+
+
+PIN CONFIGURATION NODES:
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.
+
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pin configuration subnode:
+
+- pins:
+	Usage: required

+Renesas RZ/N1 SoC Pinctrl node description.
+
+Pin controller node
+-------------------
+Required properties:
+- compatible: SoC-specific compatible string "renesas,<soc-specific>-pinctrl"
+  followed by "renesas,rzn1-pinctrl" as fallback. The SoC-specific compatible
+  strings must be one of:
+	"renesas,r9a06g032-pinctrl" for RZ/N1D
+	"renesas,r9a06g033-pinctrl" for RZ/N1S
+- reg: Address base and length of the memory area where the pin controller
+  hardware is mapped to.
+- clocks: phandle for the clock, see the description of clock-names below.
+- clock-names: Contains the name of the clock:
+    "bus", the bus clock, sometimes described as pclk, for register accesses.
+
+Example:
+	pinctrl: pin-controller@40067000 {
+	    compatible = "renesas,r9a06g032-pinctrl", "renesas,rzn1-pinctrl";
+	    reg = <0x40067000 0x1000>, <0x51000000 0x480>;
+	    clocks = <&sysctrl R9A06G032_HCLK_PINCONFIG>;
+	    clock-names = "bus";
+	};
+
+Sub-nodes
+---------
+
+The child nodes of the pin controller node describe a pin multiplexing
+function.
+
+- Pin multiplexing sub-nodes:
+  A pin multiplexing sub-node describes how to configure a set of
+  (or a single) pin in some desired alternate function mode.
+  A single sub-node may define several pin configurations.
+  Please refer to pinctrl-bindings.txt to get to know more on generic
+  pin properties usage.
+
+  The allowed generic formats for a pin multiplexing sub-node are the
+  following ones:
+
+  node-1 {
+      pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
+      GENERIC_PINCONFIG;
+  };
+
+  node-2 {
+      sub-node-1 {
+          pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
+          GENERIC_PINCONFIG;
+      };
+
+      sub-node-2 {
+          pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
+          GENERIC_PINCONFIG;
+      };
+
+      ...
+
+      sub-node-n {
+          pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
+          GENERIC_PINCONFIG;
+      };
+  };
+
+  node-3 {
+      pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
+      GENERIC_PINCONFIG;
+
+      sub-node-1 {
+          pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
+          GENERIC_PINCONFIG;
+      };
+
+      ...
+
+      sub-node-n {
+          pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
+          GENERIC_PINCONFIG;
+      };
+  };
+
+  Use the latter two formats when pins part of the same logical group need to
+  have different generic pin configuration flags applied. Note that the generic
+  pinconfig in node-3 does not apply to the sub-nodes.
+
+  Client sub-nodes shall refer to pin multiplexing sub-nodes using the phandle
+  of the most external one.
+
+  Eg.
+
+  client-1 {
+      ...
+      pinctrl-0 = <&node-1>;
+      ...
+  };
+
+  client-2 {
+      ...
+      pinctrl-0 = <&node-2>;
+      ...
+  };
+
+  Required properties:
+    - pinmux:
+      integer array representing pin number and pin multiplexing configuration.
+      When a pin has to be configured in alternate function mode, use this
+      property to identify the pin by its global index, and provide its
+      alternate function configuration number along with it.
+      When multiple pins are required to be configured as part of the same
+      alternate function they shall be specified as members of the same
+      argument list of a single "pinmux" property.
+      Integers values in the "pinmux" argument list are assembled as:
+      (PIN | MUX_FUNC << 8)
+      where PIN directly corresponds to the pl_gpio pin number and MUX_FUNC is
+      one of the alternate function identifiers defined in:
+      <include/dt-bindings/pinctrl/rzn1-pinctrl.h>
+      These identifiers collapse the IO Multiplex Configuration Level 1 and
+      Level 2 numbers that are detailed in the hardware reference manual into a
+      single number. The identifiers for Level 2 are simply offset by 10.
+      Additional identifiers are provided to specify the MDIO source peripheral.
+
+  Optional generic pinconf properties:
+    - bias-disable		- disable any pin bias
+    - bias-pull-up		- pull up the pin with 50 KOhm
+    - bias-pull-down		- pull down the pin with 50 KOhm
+    - bias-high-impedance	- high impedance mode
+    - drive-strength		- sink or source at most 4, 6, 8 or 12 mA
+
+  Example:
+  A serial communication interface with a TX output pin and an RX input pin.
+
+  &pinctrl {
+	pins_uart0: pins_uart0 {
+		pinmux = <
+			RZN1_PINMUX(103, RZN1_FUNC_UART0_I)	/* UART0_TXD */
+			RZN1_PINMUX(104, RZN1_FUNC_UART0_I)	/* UART0_RXD */
+		>;
+	};
+  };
+
+  Example 2:
+  Here we set the pull up on the RXD pin of the UART.
+
+  &pinctrl {
+	pins_uart0: pins_uart0 {
+		pinmux = <RZN1_PINMUX(103, RZN1_FUNC_UART0_I)>;	/* TXD */
+
+		pins_uart6_rx {
+			pinmux = <RZN1_PINMUX(104, RZN1_FUNC_UART0_I)>; /* RXD */
+			bias-pull-up;
+		};
+	};

+
+The Linux FireWire subsystem adds some interfaces into the Linux system to
+ use/maintain+any resource on IEEE 1394 bus.
+
+The main purpose of these interfaces is to access address space on each node
+on IEEE 1394 bus by ISO/IEC 13213 (IEEE 1212) procedure, and to control
+isochronous resources on the bus by IEEE 1394 procedure.
+
+Two types of interfaces are added, according to consumers of the interface. A
+set of userspace interfaces is available via `firewire character devices`. A set
+of kernel interfaces is available via exported symbols in `firewire-core` module.

+Arrays of pins
+--------------
+In addition to requesting pins belonging to a function one by one, a device may
+also request an array of pins assigned to the function.  The way those pins are
+mapped to the device determines if the array qualifies for fast bitmap
+processing.  If yes, a bitmap is passed over get/set array functions directly
+between a caller and a respective .get/set_multiple() callback of a GPIO chip.
+
+In order to qualify for fast bitmap processing, the array must meet the
+following requirements:
+- pin hardware number of array member 0 must also be 0,
+- pin hardware numbers of consecutive array members which belong to the same
+  chip as member 0 does must also match their array indexes.
+
+Otherwise fast bitmap processing path is not used in order to avoid consecutive
+pins which belong to the same chip but are not in hardware order being processed
+separately.
+
+If the array applies for fast bitmap processing path, pins which belong to
+different chips than member 0 does, as well as those with indexes different from
+their hardware pin numbers, are excluded from the fast path, both input and
+output.  Moreover, open drain and open source pins are excluded from fast bitmap
+output processing.

+PCI Peer-to-Peer DMA Support
+============================
+
+The PCI bus has pretty decent support for performing DMA transfers
+between two devices on the bus. This type of transaction is henceforth
+called Peer-to-Peer (or P2P). However, there are a number of issues that
+make P2P transactions tricky to do in a perfectly safe way.
+
+One of the biggest issues is that PCI doesn't require forwarding
+transactions between hierarchy domains, and in PCIe, each Root Port
+defines a separate hierarchy domain. To make things worse, there is no
+simple way to determine if a given Root Complex supports this or not.
+(See PCIe r4.0, sec 1.3.1). Therefore, as of this writing, the kernel
+only supports doing P2P when the endpoints involved are all behind the
+same PCI bridge, as such devices are all in the same PCI hierarchy
+domain, and the spec guarantees that all transactions within the
+hierarchy will be routable, but it does not require routing
+between hierarchies.
+
+The second issue is that to make use of existing interfaces in Linux,
+memory that is used for P2P transactions needs to be backed by struct
+pages. However, PCI BARs are not typically cache coherent so there are
+a few corner case gotchas with these pages so developers need to
+be careful about what they do with them.
+
+
+Driver Writer's Guide
+=====================
+
+In a given P2P implementation there may be three or more different
+types of kernel drivers in play:
+
+* Provider - A driver which provides or publishes P2P resources like
+  memory or doorbell registers to other drivers.
+* Client - A driver which makes use of a resource by setting up a
+  DMA transaction to or from it.
+* Orchestrator - A driver which orchestrates the flow of data between
+  clients and providers.
+
+In many cases there could be overlap between these three types (i.e.,
+it may be typical for a driver to be both a provider and a client).
+
+For example, in the NVMe Target Copy Offload implementation:
+
+* The NVMe PCI driver is both a client, provider and orchestrator
+  in that it exposes any CMB (Controller Memory Buffer) as a P2P memory
+  resource (provider), it accepts P2P memory pages as buffers in requests
+  to be used directly (client) and it can also make use of the CMB as
+  submission queue entries (orchastrator).
+* The RDMA driver is a client in this arrangement so that an RNIC
+  can DMA directly to the memory exposed by the NVMe device.
+* The NVMe Target driver (nvmet) can orchestrate the data from the RNIC
+  to the P2P memory (CMB) and then to the NVMe device (and vice versa).
+
+This is currently the only arrangement supported by the kernel but
+one could imagine slight tweaks to this that would allow for the same
+functionality. For example, if a specific RNIC added a BAR with some
+memory behind it, its driver could add support as a P2P provider and
+then the NVMe Target could use the RNIC's memory instead of the CMB
+in cases where the NVMe cards in use do not have CMB support.
+
+
+Provider Drivers
+----------------
+
+A provider simply needs to register a BAR (or a portion of a BAR)
+as a P2P DMA resource using :c:func:`pci_p2pdma_add_resource()`.
+This will register struct pages for all the specified memory.
+
+After that it may optionally publish all of its resources as
+P2P memory using :c:func:`pci_p2pmem_publish()`. This will allow
+any orchestrator drivers to find and use the memory. When marked in
+this way, the resource must be regular memory with no side effects.
+
+For the time being this is fairly rudimentary in that all resources
+are typically going to be P2P memory. Future work will likely expand
+this to include other types of resources like doorbells.
+
+
+Client Drivers
+--------------
+
+A client driver typically only has to conditionally change its DMA map
+routine to use the mapping function :c:func:`pci_p2pdma_map_sg()` instead
+of the usual :c:func:`dma_map_sg()` function. Memory mapped in this
+way does not need to be unmapped.
+
+The client may also, optionally, make use of
+:c:func:`is_pci_p2pdma_page()` to determine when to use the P2P mapping
+functions and when to use the regular mapping functions. In some
+situations, it may be more appropriate to use a flag to indicate a
+given request is P2P memory and map appropriately. It is important to
+ensure that struct pages that back P2P memory stay out of code that
+does not have support for them as other code may treat the pages as
+regular memory which may not be appropriate.
+
+
+Orchestrator Drivers
+--------------------
+
+The first task an orchestrator driver must do is compile a list of
+all client devices that will be involved in a given transaction. For
+example, the NVMe Target driver creates a list including the namespace
+block device and the RNIC in use. If the orchestrator has access to
+a specific P2P provider to use it may check compatibility using
+:c:func:`pci_p2pdma_distance()` otherwise it may find a memory provider
+that's compatible with all clients using  :c:func:`pci_p2pmem_find()`.
+If more than one provider is supported, the one nearest to all the clients will
+be chosen first. If more than one provider is an equal distance away, the
+one returned will be chosen at random (it is not an arbitrary but
+truely random). This function returns the PCI device to use for the provider
+with a reference taken and therefore when it's no longer needed it should be
+returned with pci_dev_put().
+
+Once a provider is selected, the orchestrator can then use
+:c:func:`pci_alloc_p2pmem()` and :c:func:`pci_free_p2pmem()` to
+allocate P2P memory from the provider. :c:func:`pci_p2pmem_alloc_sgl()`
+and :c:func:`pci_p2pmem_free_sgl()` are convenience functions for
+allocating scatter-gather lists with P2P memory.
+
+Struct Page Caveats
+-------------------
+
+Driver writers should be very careful about not passing these special
+struct pages to code that isn't prepared for it. At this time, the kernel
+interfaces do not have any checks for ensuring this. This obviously
+precludes passing these pages to userspace.
+
+P2P memory is also technically IO memory but should never have any side
+effects behind it. Thus, the order of loads and stores should not be important
+and ioreadX(), iowriteX() and friends should not be necessary.
+However, as the memory is not cache coherent, if access ever needs to
+be protected by a spinlock then :c:func:`mmiowb()` must be used before
+unlocking the lock. (See ACQUIRES VS I/O ACCESSES in
+Documentation/memory-barriers.txt)

-========================
-General Information
-========================
-
-Ext4 is an advanced level of the ext3 filesystem which incorporates
-scalability and reliability enhancements for supporting large filesystems
-(64 bit) in keeping with increasing disk capacities and state-of-the-art
-feature requirements.
-
-Mailing list:	linux-ext4@vger.kernel.org
-Web site:	http://ext4.wiki.kernel.org
-
-
-Quick usage instructions
-========================
-
-Note: More extensive information for getting started with ext4 can be
-found at the ext4 wiki site at the URL:
-http://ext4.wiki.kernel.org/index.php/Ext4_Howto
-
-  - The latest version of e2fsprogs can be found at:
-
-    https://www.kernel.org/pub/linux/kernel/people/tytso/e2fsprogs/
-
-	or
-
-    http://sourceforge.net/project/showfiles.php?group_id=2406
-
-	or grab the latest git repository from:
-
-   https://git.kernel.org/pub/scm/fs/ext2/e2fsprogs.git
-
-  - Create a new filesystem using the ext4 filesystem type:
-
-        # mke2fs -t ext4 /dev/hda1
-
-    Or to configure an existing ext3 filesystem to support extents:
-
-	# tune2fs -O extents /dev/hda1
-
-    If the filesystem was created with 128 byte inodes, it can be
-    converted to use 256 byte for greater efficiency via:
-
-        # tune2fs -I 256 /dev/hda1
-
-  - Mounting:
-
-	# mount -t ext4 /dev/hda1 /wherever
-
-  - When comparing performance with other filesystems, it's always
-    important to try multiple workloads; very often a subtle change in a
-    workload parameter can completely change the ranking of which
-    filesystems do well compared to others.  When comparing versus ext3,
-    note that ext4 enables write barriers by default, while ext3 does
-    not enable write barriers by default.  So it is useful to use
-    explicitly specify whether barriers are enabled or not when via the
-    '-o barriers=[0|1]' mount option for both ext3 and ext4 filesystems
-    for a fair comparison.  When tuning ext3 for best benchmark numbers,
-    it is often worthwhile to try changing the data journaling mode; '-o
-    data=writeback' can be faster for some workloads.  (Note however that
-    running mounted with data=writeback can potentially leave stale data
-    exposed in recently written files in case of an unclean shutdown,
-    which could be a security exposure in some situations.)  Configuring
-    the filesystem with a large journal can also be helpful for
-    metadata-intensive workloads.
-
-Features
-========
-
-Currently Available
--------------------
-
-* ability to use filesystems > 16TB (e2fsprogs support not available yet)
-* extent format reduces metadata overhead (RAM, IO for access, transactions)
-* extent format more robust in face of on-disk corruption due to magics,
-* internal redundancy in tree
-* improved file allocation (multi-block alloc)
-* lift 32000 subdirectory limit imposed by i_links_count[1]
-* nsec timestamps for mtime, atime, ctime, create time
-* inode version field on disk (NFSv4, Lustre)
-* reduced e2fsck time via uninit_bg feature
-* journal checksumming for robustness, performance
-* persistent file preallocation (e.g for streaming media, databases)
-* ability to pack bitmaps and inode tables into larger virtual groups via the
-  flex_bg feature
-* large file support
-* inode allocation using large virtual block groups via flex_bg
-* delayed allocation
-* large block (up to pagesize) support
-* efficient new ordered mode in JBD2 and ext4 (avoid using buffer head to force
-  the ordering)
-
-[1] Filesystems with a block size of 1k may see a limit imposed by the
-directory hash tree having a maximum depth of two.

-Options
-=======
-
-When mounting an ext4 filesystem, the following option are accepted:
-(*) == default
-
-======================= =======================================================
-Mount Option            Description
-======================= =======================================================
-ro                   	Mount filesystem read only. Note that ext4 will
-                     	replay the journal (and thus write to the
-                     	partition) even when mounted "read only". The
-                     	mount options "ro,noload" can be used to prevent
-		     	writes to the filesystem.
-
-journal_checksum	Enable checksumming of the journal transactions.
-			This will allow the recovery code in e2fsck and the
-			kernel to detect corruption in the kernel.  It is a
-			compatible change and will be ignored by older kernels.
-
-journal_async_commit	Commit block can be written to disk without waiting
-			for descriptor blocks. If enabled older kernels cannot
-			mount the device. This will enable 'journal_checksum'
-			internally.
-
-journal_path=path
-journal_dev=devnum	When the external journal device's major/minor numbers
-			have changed, these options allow the user to specify
-			the new journal location.  The journal device is
-			identified through either its new major/minor numbers
-			encoded in devnum, or via a path to the device.
-
-norecovery		Don't load the journal on mounting.  Note that
-noload			if the filesystem was not unmounted cleanly,
-                     	skipping the journal replay will lead to the
-                     	filesystem containing inconsistencies that can
-                     	lead to any number of problems.
-
-data=journal		All data are committed into the journal prior to being
-			written into the main file system.  Enabling
-			this mode will disable delayed allocation and
-			O_DIRECT support.
-
-data=ordered	(*)	All data are forced directly out to the main file
-			system prior to its metadata being committed to the
-			journal.
-
-data=writeback		Data ordering is not preserved, data may be written
-			into the main file system after its metadata has been
-			committed to the journal.
-
-commit=nrsec	(*)	Ext4 can be told to sync all its data and metadata
-			every 'nrsec' seconds. The default value is 5 seconds.
-			This means that if you lose your power, you will lose
-			as much as the latest 5 seconds of work (your
-			filesystem will not be damaged though, thanks to the
-			journaling).  This default value (or any low value)
-			will hurt performance, but it's good for data-safety.
-			Setting it to 0 will have the same effect as leaving
-			it at the default (5 seconds).
-			Setting it to very large values will improve
-			performance.
-
-barrier=<0|1(*)>	This enables/disables the use of write barriers in
-barrier(*)		the jbd code.  barrier=0 disables, barrier=1 enables.
-nobarrier		This also requires an IO stack which can support
-			barriers, and if jbd gets an error on a barrier
-			write, it will disable again with a warning.
-			Write barriers enforce proper on-disk ordering
-			of journal commits, making volatile disk write caches
-			safe to use, at some performance penalty.  If
-			your disks are battery-backed in one way or another,
-			disabling barriers may safely improve performance.
-			The mount options "barrier" and "nobarrier" can
-			also be used to enable or disable barriers, for
-			consistency with other ext4 mount options.
-
-inode_readahead_blks=n	This tuning parameter controls the maximum
-			number of inode table blocks that ext4's inode
-			table readahead algorithm will pre-read into
-			the buffer cache.  The default value is 32 blocks.
-
-nouser_xattr		Disables Extended User Attributes.  See the
-			attr(5) manual page for more information about
-			extended attributes.
-
-noacl			This option disables POSIX Access Control List
-			support. If ACL support is enabled in the kernel
-			configuration (CONFIG_EXT4_FS_POSIX_ACL), ACL is
-			enabled by default on mount. See the acl(5) manual
-			page for more information about acl.
-
-bsddf		(*)	Make 'df' act like BSD.
-minixdf			Make 'df' act like Minix.
-
-debug			Extra debugging information is sent to syslog.
-
-abort			Simulate the effects of calling ext4_abort() for
-			debugging purposes.  This is normally used while
-			remounting a filesystem which is already mounted.
-
-errors=remount-ro	Remount the filesystem read-only on an error.
-errors=continue		Keep going on a filesystem error.
-errors=panic		Panic and halt the machine if an error occurs.
-                        (These mount options override the errors behavior
-                        specified in the superblock, which can be configured
-                        using tune2fs)
-
-data_err=ignore(*)	Just print an error message if an error occurs
-			in a file data buffer in ordered mode.
-data_err=abort		Abort the journal if an error occurs in a file
-			data buffer in ordered mode.
-
-grpid			New objects have the group ID of their parent.
-bsdgroups
-
-nogrpid		(*)	New objects have the group ID of their creator.
-sysvgroups
-
-resgid=n		The group ID which may use the reserved blocks.
-
-resuid=n		The user ID which may use the reserved blocks.
-
-sb=n			Use alternate superblock at this location.
-
-quota			These options are ignored by the filesystem. They
-noquota			are used only by quota tools to recognize volumes
-grpquota		where quota should be turned on. See documentation
-usrquota		in the quota-tools package for more details
-			(http://sourceforge.net/projects/linuxquota).
-
-jqfmt=<quota type>	These options tell filesystem details about quota
-usrjquota=<file>	so that quota information can be properly updated
-grpjquota=<file>	during journal replay. They replace the above
-			quota options. See documentation in the quota-tools
-			package for more details
-			(http://sourceforge.net/projects/linuxquota).
-
-stripe=n		Number of filesystem blocks that mballoc will try
-			to use for allocation size and alignment. For RAID5/6
-			systems this should be the number of data
-			disks *  RAID chunk size in file system blocks.
-
-delalloc	(*)	Defer block allocation until just before ext4
-			writes out the block(s) in question.  This
-			allows ext4 to better allocation decisions
-			more efficiently.
-nodelalloc		Disable delayed allocation.  Blocks are allocated
-			when the data is copied from userspace to the
-			page cache, either via the write(2) system call
-			or when an mmap'ed page which was previously
-			unallocated is written for the first time.
-
-max_batch_time=usec	Maximum amount of time ext4 should wait for
-			additional filesystem operations to be batch
-			together with a synchronous write operation.
-			Since a synchronous write operation is going to
-			force a commit and then a wait for the I/O
-			complete, it doesn't cost much, and can be a
-			huge throughput win, we wait for a small amount
-			of time to see if any other transactions can
-			piggyback on the synchronous write.   The
-			algorithm used is designed to automatically tune
-			for the speed of the disk, by measuring the
-			amount of time (on average) that it takes to
-			finish committing a transaction.  Call this time
-			the "commit time".  If the time that the
-			transaction has been running is less than the
-			commit time, ext4 will try sleeping for the
-			commit time to see if other operations will join
-			the transaction.   The commit time is capped by
-			the max_batch_time, which defaults to 15000us
-			(15ms).   This optimization can be turned off
-			entirely by setting max_batch_time to 0.
-
-min_batch_time=usec	This parameter sets the commit time (as
-			described above) to be at least min_batch_time.
-			It defaults to zero microseconds.  Increasing
-			this parameter may improve the throughput of
-			multi-threaded, synchronous workloads on very
-			fast disks, at the cost of increasing latency.
-
-journal_ioprio=prio	The I/O priority (from 0 to 7, where 0 is the
-			highest priority) which should be used for I/O
-			operations submitted by kjournald2 during a
-			commit operation.  This defaults to 3, which is
-			a slightly higher priority than the default I/O
-			priority.
-
-auto_da_alloc(*)	Many broken applications don't use fsync() when 
-noauto_da_alloc		replacing existing files via patterns such as
-			fd = open("foo.new")/write(fd,..)/close(fd)/
-			rename("foo.new", "foo"), or worse yet,
-			fd = open("foo", O_TRUNC)/write(fd,..)/close(fd).
-			If auto_da_alloc is enabled, ext4 will detect
-			the replace-via-rename and replace-via-truncate
-			patterns and force that any delayed allocation
-			blocks are allocated such that at the next
-			journal commit, in the default data=ordered
-			mode, the data blocks of the new file are forced
-			to disk before the rename() operation is
-			committed.  This provides roughly the same level
-			of guarantees as ext3, and avoids the
-			"zero-length" problem that can happen when a
-			system crashes before the delayed allocation
-			blocks are forced to disk.
-
-noinit_itable		Do not initialize any uninitialized inode table
-			blocks in the background.  This feature may be
-			used by installation CD's so that the install
-			process can complete as quickly as possible; the
-			inode table initialization process would then be
-			deferred until the next time the  file system
-			is unmounted.
-
-init_itable=n		The lazy itable init code will wait n times the
-			number of milliseconds it took to zero out the
-			previous block group's inode table.  This
-			minimizes the impact on the system performance
-			while file system's inode table is being initialized.
-
-discard			Controls whether ext4 should issue discard/TRIM
-nodiscard(*)		commands to the underlying block device when
-			blocks are freed.  This is useful for SSD devices
-			and sparse/thinly-provisioned LUNs, but it is off
-			by default until sufficient testing has been done.
-
-nouid32			Disables 32-bit UIDs and GIDs.  This is for
-			interoperability  with  older kernels which only
-			store and expect 16-bit values.
-
-block_validity(*)	These options enable or disable the in-kernel
-noblock_validity	facility for tracking filesystem metadata blocks
-			within internal data structures.  This allows multi-
-			block allocator and other routines to notice
-			bugs or corrupted allocation bitmaps which cause
-			blocks to be allocated which overlap with
-			filesystem metadata blocks.
-
-dioread_lock		Controls whether or not ext4 should use the DIO read
-dioread_nolock		locking. If the dioread_nolock option is specified
-			ext4 will allocate uninitialized extent before buffer
-			write and convert the extent to initialized after IO
-			completes. This approach allows ext4 code to avoid
-			using inode mutex, which improves scalability on high
-			speed storages. However this does not work with
-			data journaling and dioread_nolock option will be
-			ignored with kernel warning. Note that dioread_nolock
-			code path is only used for extent-based files.
-			Because of the restrictions this options comprises
-			it is off by default (e.g. dioread_lock).
-
-max_dir_size_kb=n	This limits the size of directories so that any
-			attempt to expand them beyond the specified
-			limit in kilobytes will cause an ENOSPC error.
-			This is useful in memory constrained
-			environments, where a very large directory can
-			cause severe performance problems or even
-			provoke the Out Of Memory killer.  (For example,
-			if there is only 512mb memory available, a 176mb
-			directory may seriously cramp the system's style.)
-
-i_version		Enable 64-bit inode version support. This option is
-			off by default.
-
-dax			Use direct access (no page cache).  See
-			Documentation/filesystems/dax.txt.  Note that
-			this option is incompatible with data=journal.
-======================= =======================================================
-
-Data Mode
-=========
-There are 3 different data modes:
-
-* writeback mode
-
-  In data=writeback mode, ext4 does not journal data at all.  This mode provides
-  a similar level of journaling as that of XFS, JFS, and ReiserFS in its default
-  mode - metadata journaling.  A crash+recovery can cause incorrect data to
-  appear in files which were written shortly before the crash.  This mode will
-  typically provide the best ext4 performance.
-
-* ordered mode
-
-  In data=ordered mode, ext4 only officially journals metadata, but it logically
-  groups metadata information related to data changes with the data blocks into
-  a single unit called a transaction.  When it's time to write the new metadata
-  out to disk, the associated data blocks are written first.  In general, this
-  mode performs slightly slower than writeback but significantly faster than
-  journal mode.
-
-* journal mode
-
-  data=journal mode provides full data and metadata journaling.  All new data is
-  written to the journal first, and then to its final location.  In the event of
-  a crash, the journal can be replayed, bringing both data and metadata into a
-  consistent state.  This mode is the slowest except when data needs to be read
-  from and written to disk at the same time where it outperforms all others
-  modes.  Enabling this mode will disable delayed allocation and O_DIRECT
-  support.

-Ioctls
-======
-
-There is some Ext4 specific functionality which can be accessed by applications
-through the system call interfaces. The list of all Ext4 specific ioctls are
-shown in the table below.
-
-Table of Ext4 specific ioctls
-
-============================= =================================================
-Ioctl			      Description
-============================= =================================================
- EXT4_IOC_GETFLAGS	      Get additional attributes associated with inode.
-			      The ioctl argument is an integer bitfield, with
-			      bit values described in ext4.h. This ioctl is an
-			      alias for FS_IOC_GETFLAGS.
-
- EXT4_IOC_SETFLAGS	      Set additional attributes associated with inode.
-			      The ioctl argument is an integer bitfield, with
-			      bit values described in ext4.h. This ioctl is an
-			      alias for FS_IOC_SETFLAGS.
-
- EXT4_IOC_GETVERSION
- EXT4_IOC_GETVERSION_OLD
-			      Get the inode i_generation number stored for
-			      each inode. The i_generation number is normally
-			      changed only when new inode is created and it is
-			      particularly useful for network filesystems. The
-			      '_OLD' version of this ioctl is an alias for
-			      FS_IOC_GETVERSION.
-
- EXT4_IOC_SETVERSION
- EXT4_IOC_SETVERSION_OLD
-			      Set the inode i_generation number stored for
-			      each inode. The '_OLD' version of this ioctl
-			      is an alias for FS_IOC_SETVERSION.
-
- EXT4_IOC_GROUP_EXTEND	      This ioctl has the same purpose as the resize
-			      mount option. It allows to resize filesystem
-			      to the end of the last existing block group,
-			      further resize has to be done with resize2fs,
-			      either online, or offline. The argument points
-			      to the unsigned logn number representing the
-			      filesystem new block count.
-
- EXT4_IOC_MOVE_EXT	      Move the block extents from orig_fd (the one
-			      this ioctl is pointing to) to the donor_fd (the
-			      one specified in move_extent structure passed
-			      as an argument to this ioctl). Then, exchange
-			      inode metadata between orig_fd and donor_fd.
-			      This is especially useful for online
-			      defragmentation, because the allocator has the
-			      opportunity to allocate moved blocks better,
-			      ideally into one contiguous extent.
-
- EXT4_IOC_GROUP_ADD	      Add a new group descriptor to an existing or
-			      new group descriptor block. The new group
-			      descriptor is described by ext4_new_group_input
-			      structure, which is passed as an argument to
-			      this ioctl. This is especially useful in
-			      conjunction with EXT4_IOC_GROUP_EXTEND,
-			      which allows online resize of the filesystem
-			      to the end of the last existing block group.
-			      Those two ioctls combined is used in userspace
-			      online resize tool (e.g. resize2fs).
-
- EXT4_IOC_MIGRATE	      This ioctl operates on the filesystem itself.
-			      It converts (migrates) ext3 indirect block mapped
-			      inode to ext4 extent mapped inode by walking
-			      through indirect block mapping of the original
-			      inode and converting contiguous block ranges
-			      into ext4 extents of the temporary inode. Then,
-			      inodes are swapped. This ioctl might help, when
-			      migrating from ext3 to ext4 filesystem, however
-			      suggestion is to create fresh ext4 filesystem
-			      and copy data from the backup. Note, that
-			      filesystem has to support extents for this ioctl
-			      to work.
-
- EXT4_IOC_ALLOC_DA_BLKS	      Force all of the delay allocated blocks to be
-			      allocated to preserve application-expected ext3
-			      behaviour. Note that this will also start
-			      triggering a write of the data blocks, but this
-			      behaviour may change in the future as it is
-			      not necessary and has been done this way only
-			      for sake of simplicity.
-
- EXT4_IOC_RESIZE_FS	      Resize the filesystem to a new size.  The number
-			      of blocks of resized filesystem is passed in via
-			      64 bit integer argument.  The kernel allocates
-			      bitmaps and inode table, the userspace tool thus
-			      just passes the new number of blocks.
-
- EXT4_IOC_SWAP_BOOT	      Swap i_blocks and associated attributes
-			      (like i_blocks, i_size, i_flags, ...) from
-			      the specified inode with inode
-			      EXT4_BOOT_LOADER_INO (#5). This is typically
-			      used to store a boot loader in a secure part of
-			      the filesystem, where it can't be changed by a
-			      normal user by accident.
-			      The data blocks of the previous boot loader
-			      will be associated with the given inode.

-About this document
-===================
-
-Some notes about Marvell's NAND controller available in PXA and Armada 370/XP
-SoC (aka NFCv1 and NFCv2), with an emphasis on the latter.
-
-NFCv2 controller background
-===========================
-
-The controller has a 2176 bytes FIFO buffer. Therefore, in order to support
-larger pages, I/O operations on 4 KiB and 8 KiB pages is done with a set of
-chunked transfers.
-
-For instance, if we choose a 2048 data chunk and set "BCH" ECC (see below)
-we'll have this layout in the pages:
-
-  ------------------------------------------------------------------------------
-  | 2048B data | 32B spare | 30B ECC || 2048B data | 32B spare | 30B ECC | ... |
-  ------------------------------------------------------------------------------
-
-The driver reads the data and spare portions independently and builds an internal
-buffer with this layout (in the 4 KiB page case):
-
-  ------------------------------------------
-  |     4096B data     |     64B spare     |
-  ------------------------------------------
-
-Also, for the READOOB command the driver disables the ECC and reads a 'spare + ECC'
-OOB, one per chunk read.
-
-  -------------------------------------------------------------------
-  |     4096B data     |  32B spare | 30B ECC | 32B spare | 30B ECC |
-  -------------------------------------------------------------------
-
-So, in order to achieve reading (for instance), we issue several READ0 commands
-(with some additional controller-specific magic) and read two chunks of 2080B
-(2048 data + 32 spare) each.
-The driver accommodates this data to expose the NAND core a contiguous buffer
-(4096 data + spare) or (4096 + spare + ECC + spare + ECC).
-
-ECC
-===
-
-The controller has built-in hardware ECC capabilities. In addition it is
-configurable between two modes: 1) Hamming, 2) BCH.
-
-Note that the actual BCH mode: BCH-4 or BCH-8 will depend on the way
-the controller is configured to transfer the data.
-
-In the BCH mode the ECC code will be calculated for each transferred chunk
-and expected to be located (when reading/programming) right after the spare
-bytes as the figure above shows.
-
-So, repeating the above scheme, a 2048B data chunk will be followed by 32B
-spare, and then the ECC controller will read/write the ECC code (30B in
-this case):
-
-  ------------------------------------
-  | 2048B data | 32B spare | 30B ECC |
-  ------------------------------------
-
-If the ECC mode is 'BCH' then the ECC is *always* 30 bytes long.
-If the ECC mode is 'Hamming' the ECC is 6 bytes long, for each 512B block.
-So in Hamming mode, a 2048B page will have a 24B ECC.
-
-Despite all of the above, the controller requires the driver to only read or
-write in multiples of 8-bytes, because the data buffer is 64-bits.
-
-OOB
-===
-
-Because of the above scheme, and because the "spare" OOB is really located in
-the middle of a page, spare OOB cannot be read or write independently of the
-data area. In other words, in order to read the OOB (aka READOOB), the entire
-page (aka READ0) has to be read.
-
-In the same sense, in order to write to the spare OOB the driver has to write
-an *entire* page.
-
-Factory bad blocks handling
-===========================
-
-Given the ECC BCH requires to layout the device's pages in a split
-data/OOB/data/OOB way, the controller has a view of the flash page that's
-different from the specified (aka the manufacturer's) view. In other words,
-
-Factory view:
-
-  -----------------------------------------------
-  |                    Data           |x  OOB   |
-  -----------------------------------------------
-
-Driver's view:
-
-  -----------------------------------------------
-  |      Data      | OOB |      Data   x  | OOB |
-  -----------------------------------------------
-
-It can be seen from the above, that the factory bad block marker must be
-searched within the 'data' region, and not in the usual OOB region.
-
-In addition, this means under regular usage the driver will write such
-position (since it belongs to the data region) and every used block is
-likely to be marked as bad.
-
-For this reason, marking the block as bad in the OOB is explicitly
-disabled by using the NAND_BBT_NO_OOB_BBM option in the driver. The rationale
-for this is that there's no point in marking a block as bad, because good
-blocks are also 'marked as bad' (in the OOB BBM sense) under normal usage.
-
-Instead, the driver relies on the bad block table alone, and should only perform
-the bad block scan on the very first time (when the device hasn't been used).

+Notes on the DEC FDDIcontroller 700 (DEFZA-xx) driver v.1.1.4.
+
+
+DEC FDDIcontroller 700 is DEC's first-generation TURBOchannel FDDI
+network card, designed in 1990 specifically for the DECstation 5000
+model 200 workstation.  The board is a single attachment station and
+it was manufactured in two variations, both of which are supported.
+
+First is the SAS MMF DEFZA-AA option, the original design implementing
+the standard MMF-PMD, however with a pair of ST connectors rather than
+the usual MIC connector.  The other one is the SAS ThinWire/STP DEFZA-CA
+option, denoted 700-C, with the network medium selectable by a switch
+between the DEC proprietary ThinWire-PMD using a BNC connector and the
+standard STP-PMD using a DE-9F connector.  This option can interface to
+a DECconcentrator 500 device and, in the case of the STP-PMD, also other
+FDDI equipment and was designed to make it easier to transition from
+existing IEEE 802.3 10BASE2 Ethernet and IEEE 802.5 Token Ring networks
+by providing means to reuse existing cabling.
+
+This driver handles any number of cards installed in a single system.
+They get fddi0, fddi1, etc. interface names assigned in the order of
+increasing TURBOchannel slot numbers.
+
+The board only supports DMA on the receive side.  Transmission involves
+the use of PIO.  As a result under a heavy transmission load there will
+be a significant impact on system performance.
+
+The board supports a 64-entry CAM for matching destination addresses.
+Two entries are preoccupied by the Directed Beacon and Ring Purger
+multicast addresses and the rest is used as a multicast filter.  An
+all-multi mode is also supported for LLC frames and it is used if
+requested explicitly or if the CAM overflows.  The promiscuous mode
+supports separate enables for LLC and SMT frames, but this driver
+doesn't support changing them individually.
+
+
+Known problems:
+
+None.
+
+
+To do:
+
+5. MAC address change.  The card does not support changing the Media
+   Access Controller's address registers but a similar effect can be
+   achieved by adding an alias to the CAM.  There is no way to disable
+   matching against the original address though.
+
+7. Queueing incoming/outgoing SMT frames in the driver if the SMT
+   receive/RMC transmit ring is full. (?)
+
+8. Retrieving/reporting FDDI/SNMP stats.
+
+
+Both success and failure reports are welcome.

+Identifying Your Adapter
+========================
+For information on how to identify your adapter, and for the latest Intel
+network drivers, refer to the Intel Support website:
+https://www.intel.com/support
+
+
+Command Line Parameters
+=======================
+If the driver is built as a module, the following optional parameters are used
+by entering them on the command line with the modprobe command using this
+syntax::
+
+    modprobe e1000e [<option>=<VAL1>,<VAL2>,...]
+
+There needs to be a <VAL#> for each network port in the system supported by
+this driver. The values will be applied to each instance, in function order.
+For example::
+
+    modprobe e1000e InterruptThrottleRate=16000,16000
+
+In this case, there are two network ports supported by e1000e in the system.
+The default value for each parameter is generally the recommended setting,
+unless otherwise noted.
+
+NOTE: A descriptor describes a data buffer and attributes related to the data
+buffer. This information is accessed by the hardware.
+
+InterruptThrottleRate
+---------------------
+:Valid Range: 0,1,3,4,100-100000
+:Default Value: 3
+
+Interrupt Throttle Rate controls the number of interrupts each interrupt
+vector can generate per second. Increasing ITR lowers latency at the cost of
+increased CPU utilization, though it may help throughput in some circumstances.
+
+Setting InterruptThrottleRate to a value greater or equal to 100
+will program the adapter to send out a maximum of that many interrupts
+per second, even if more packets have come in. This reduces interrupt
+load on the system and can lower CPU utilization under heavy load,
+but will increase latency as packets are not processed as quickly.
+
+The default behaviour of the driver previously assumed a static
+InterruptThrottleRate value of 8000, providing a good fallback value for
+all traffic types, but lacking in small packet performance and latency.
+The hardware can handle many more small packets per second however, and
+for this reason an adaptive interrupt moderation algorithm was implemented.
+
+The driver has two adaptive modes (setting 1 or 3) in which
+it dynamically adjusts the InterruptThrottleRate value based on the traffic
+that it receives. After determining the type of incoming traffic in the last
+timeframe, it will adjust the InterruptThrottleRate to an appropriate value
+for that traffic.
+
+The algorithm classifies the incoming traffic every interval into
+classes.  Once the class is determined, the InterruptThrottleRate value is
+adjusted to suit that traffic type the best. There are three classes defined:
+"Bulk traffic", for large amounts of packets of normal size; "Low latency",
+for small amounts of traffic and/or a significant percentage of small
+packets; and "Lowest latency", for almost completely small packets or
+minimal traffic.
+
+ - 0: Off
+      Turns off any interrupt moderation and may improve small packet latency.
+      However, this is generally not suitable for bulk throughput traffic due
+      to the increased CPU utilization of the higher interrupt rate.
+ - 1: Dynamic mode
+      This mode attempts to moderate interrupts per vector while maintaining
+      very low latency. This can sometimes cause extra CPU utilization. If
+      planning on deploying e1000e in a latency sensitive environment, this
+      parameter should be considered.
+ - 3: Dynamic Conservative mode (default)
+      In dynamic conservative mode, the InterruptThrottleRate value is set to
+      4000 for traffic that falls in class "Bulk traffic". If traffic falls in
+      the "Low latency" or "Lowest latency" class, the InterruptThrottleRate is
+      increased stepwise to 20000. This default mode is suitable for most
+      applications.
+ - 4: Simplified Balancing mode
+      In simplified mode the interrupt rate is based on the ratio of TX and
+      RX traffic.  If the bytes per second rate is approximately equal, the
+      interrupt rate will drop as low as 2000 interrupts per second.  If the
+      traffic is mostly transmit or mostly receive, the interrupt rate could
+      be as high as 8000.
+ - 100-100000:
+      Setting InterruptThrottleRate to a value greater or equal to 100
+      will program the adapter to send at most that many interrupts per second,
+      even if more packets have come in. This reduces interrupt load on the
+      system and can lower CPU utilization under heavy load, but will increase
+      latency as packets are not processed as quickly.
+
+NOTE: InterruptThrottleRate takes precedence over the TxAbsIntDelay and
+RxAbsIntDelay parameters. In other words, minimizing the receive and/or
+transmit absolute delays does not force the controller to generate more
+interrupts than what the Interrupt Throttle Rate allows.
+
+RxIntDelay
+----------
+:Valid Range: 0-65535 (0=off)
+:Default Value: 0
+
+This value delays the generation of receive interrupts in units of 1.024
+microseconds. Receive interrupt reduction can improve CPU efficiency if
+properly tuned for specific network traffic. Increasing this value adds extra
+latency to frame reception and can end up decreasing the throughput of TCP
+traffic. If the system is reporting dropped receives, this value may be set
+too high, causing the driver to run out of available receive descriptors.
+
+CAUTION: When setting RxIntDelay to a value other than 0, adapters may hang
+(stop transmitting) under certain network conditions. If this occurs a NETDEV
+WATCHDOG message is logged in the system event log. In addition, the
+controller is automatically reset, restoring the network connection. To
+eliminate the potential for the hang ensure that RxIntDelay is set to 0.
+
+RxAbsIntDelay
+-------------
+:Valid Range: 0-65535 (0=off)
+:Default Value: 8
+
+This value, in units of 1.024 microseconds, limits the delay in which a
+receive interrupt is generated. This value ensures that an interrupt is
+generated after the initial packet is received within the set amount of time,
+which is useful only if RxIntDelay is non-zero. Proper tuning, along with
+RxIntDelay, may improve traffic throughput in specific network conditions.
+
+TxIntDelay
+----------
+:Valid Range: 0-65535 (0=off)
+:Default Value: 8
+
+This value delays the generation of transmit interrupts in units of 1.024
+microseconds. Transmit interrupt reduction can improve CPU efficiency if
+properly tuned for specific network traffic. If the system is reporting
+dropped transmits, this value may be set too high causing the driver to run
+out of available transmit descriptors.
+
+TxAbsIntDelay
+-------------
+:Valid Range: 0-65535 (0=off)
+:Default Value: 32
+
+This value, in units of 1.024 microseconds, limits the delay in which a
+transmit interrupt is generated. It is useful only if TxIntDelay is non-zero.
+It ensures that an interrupt is generated after the initial Packet is sent on
+the wire within the set amount of time. Proper tuning, along with TxIntDelay,
+may improve traffic throughput in specific network conditions.
+
+copybreak
+---------
+:Valid Range: 0-xxxxxxx (0=off)
+:Default Value: 256
+
+The driver copies all packets below or equaling this size to a fresh receive
+buffer before handing it up the stack.
+This parameter differs from other parameters because it is a single (not 1,1,1
+etc.) parameter applied to all driver instances and it is also available
+during runtime at /sys/module/e1000e/parameters/copybreak.
+
+To use copybreak, type::
+
+    modprobe e1000e.ko copybreak=128
+
+SmartPowerDownEnable
+--------------------
+:Valid Range: 0,1
+:Default Value: 0 (disabled)
+
+Allows the PHY to turn off in lower power states. The user can turn off this
+parameter in supported chipsets.
+
+KumeranLockLoss
+---------------
+:Valid Range: 0,1
+:Default Value: 1 (enabled)
+
+This workaround skips resetting the PHY at shutdown for the initial silicon
+releases of ICH8 systems.
+
+IntMode
+-------
+:Valid Range: 0-2
+:Default Value: 0
+
+   +-------+----------------+
+   | Value | Interrupt Mode |
+   +=======+================+
+   |   0   |     Legacy     |
+   +-------+----------------+
+   |   1   |       MSI      |
+   +-------+----------------+
+   |   2   |      MSI-X     |
+   +-------+----------------+
+
+IntMode allows load time control over the type of interrupt registered for by
+the driver. MSI-X is required for multiple queue support, and some kernels and
+combinations of kernel .config options will force a lower level of interrupt
+support.
+
+This command will show different values for each type of interrupt::
+
+  cat /proc/interrupts
+
+CrcStripping
+------------
+:Valid Range: 0,1
+:Default Value: 1 (enabled)
+
+Strip the CRC from received packets before sending up the network stack. If
+you have a machine with a BMC enabled but cannot receive IPMI traffic after
+loading or enabling the driver, try disabling this feature.
+
+WriteProtectNVM
+---------------
+:Valid Range: 0,1
+:Default Value: 1 (enabled)
+
+If set to 1, configure the hardware to ignore all write/erase cycles to the
+GbE region in the ICHx NVM (in order to prevent accidental corruption of the
+NVM). This feature can be disabled by setting the parameter to 0 during initial
+driver load.
+
+NOTE: The machine must be power cycled (full off/on) when enabling NVM writes
+via setting the parameter to zero. Once the NVM has been locked (via the
+parameter at 1 when the driver loads) it cannot be unlocked except via power
+cycle.
+
+Debug
+-----
+:Valid Range: 0-16 (0=none,...,16=all)
+:Default Value: 0
+
+This parameter adjusts the level of debug messages displayed in the system logs.
+
+
+Additional Features and Configurations
+======================================
+
+Jumbo Frames
+------------
+Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)
+to a value larger than the default value of 1500.
+
+Use the ifconfig command to increase the MTU size. For example, enter the
+following where <x> is the interface number::
+
+    ifconfig eth<x> mtu 9000 up
+
+Alternatively, you can use the ip command as follows::
+
+    ip link set mtu 9000 dev eth<x>
+    ip link set up dev eth<x>
+
+This setting is not saved across reboots. The setting change can be made
+permanent by adding 'MTU=9000' to the file:
+
+- For RHEL: /etc/sysconfig/network-scripts/ifcfg-eth<x>
+- For SLES: /etc/sysconfig/network/<config_file>
+
+NOTE: The maximum MTU setting for Jumbo Frames is 8996. This value coincides
+with the maximum Jumbo Frames size of 9018 bytes.

+
+ethtool
+-------
+The driver utilizes the ethtool interface for driver configuration and
+diagnostics, as well as displaying statistical information. The latest ethtool
+version is required for this functionality. Download it at:
+
+https://www.kernel.org/pub/software/network/ethtool/
+
+NOTE: When validating enable/disable tests on some parts (for example, 82578),
+it is necessary to add a few seconds between tests when working with ethtool.
+
+
+Speed and Duplex Configuration
+------------------------------
+In addressing speed and duplex configuration issues, you need to distinguish
+between copper-based adapters and fiber-based adapters.
+
+In the default mode, an Intel(R) Ethernet Network Adapter using copper
+connections will attempt to auto-negotiate with its link partner to determine
+the best setting. If the adapter cannot establish link with the link partner
+using auto-negotiation, you may need to manually configure the adapter and link
+partner to identical settings to establish link and pass packets. This should
+only be needed when attempting to link with an older switch that does not
+support auto-negotiation or one that has been forced to a specific speed or
+duplex mode. Your link partner must match the setting you choose. 1 Gbps speeds
+and higher cannot be forced. Use the autonegotiation advertising setting to
+manually set devices for 1 Gbps and higher.
+
+Speed, duplex, and autonegotiation advertising are configured through the
+ethtool* utility.
+
+Caution: Only experienced network administrators should force speed and duplex
+or change autonegotiation advertising manually. The settings at the switch must
+always match the adapter settings. Adapter performance may suffer or your
+adapter may not operate if you configure the adapter differently from your
+switch.
+
+An Intel(R) Ethernet Network Adapter using fiber-based connections, however,
+will not attempt to auto-negotiate with its link partner since those adapters
+operate only in full duplex and only at their native speed.
+
+
+Enabling Wake on LAN* (WoL)
+---------------------------
+WoL is configured through the ethtool* utility.
+
+WoL will be enabled on the system during the next shut down or reboot. For
+this driver version, in order to enable WoL, the e1000e driver must be loaded
+prior to shutting down or suspending the system.
+
+NOTE: Wake on LAN is only supported on port A for the following devices:
+- Intel(R) PRO/1000 PT Dual Port Network Connection
+- Intel(R) PRO/1000 PT Dual Port Server Connection
+- Intel(R) PRO/1000 PT Dual Port Server Adapter
+- Intel(R) PRO/1000 PF Dual Port Server Adapter

-Identifying Your Adapter
-========================
-
-The e1000e driver supports all PCI Express Intel(R) Gigabit Network
-Connections, except those that are 82575, 82576 and 82580-based*.
-
-* NOTE: The Intel(R) PRO/1000 P Dual Port Server Adapter is supported by
-  the e1000 driver, not the e1000e driver due to the 82546 part being used
-  behind a PCI Express bridge.
-
-For more information on how to identify your adapter, go to the Adapter &
-Driver ID Guide at:
-
-    http://support.intel.com/support/go/network/adapter/idguide.htm
-
-For the latest Intel network drivers for Linux, refer to the following
-website.  In the search field, enter your adapter name or type, or use the
-networking link on the left to search for your adapter:

-
-Command Line Parameters
-=======================
-
-The default value for each parameter is generally the recommended setting,
-unless otherwise noted.
-
-NOTES:  For more information about the InterruptThrottleRate,
-        RxIntDelay, TxIntDelay, RxAbsIntDelay, and TxAbsIntDelay
-        parameters, see the application note at:
-        http://www.intel.com/design/network/applnots/ap450.htm
-
-InterruptThrottleRate
----------------------
-Valid Range:   0,1,3,4,100-100000 (0=off, 1=dynamic, 3=dynamic conservative,
-                                   4=simplified balancing)
-Default Value: 3
-
-The driver can limit the amount of interrupts per second that the adapter
-will generate for incoming packets. It does this by writing a value to the
-adapter that is based on the maximum amount of interrupts that the adapter
-will generate per second.
-
-Setting InterruptThrottleRate to a value greater or equal to 100
-will program the adapter to send out a maximum of that many interrupts
-per second, even if more packets have come in. This reduces interrupt
-load on the system and can lower CPU utilization under heavy load,
-but will increase latency as packets are not processed as quickly.
-
-The default behaviour of the driver previously assumed a static
-InterruptThrottleRate value of 8000, providing a good fallback value for
-all traffic types, but lacking in small packet performance and latency.
-The hardware can handle many more small packets per second however, and
-for this reason an adaptive interrupt moderation algorithm was implemented.
-
-The driver has two adaptive modes (setting 1 or 3) in which
-it dynamically adjusts the InterruptThrottleRate value based on the traffic
-that it receives. After determining the type of incoming traffic in the last
-timeframe, it will adjust the InterruptThrottleRate to an appropriate value
-for that traffic.
-
-The algorithm classifies the incoming traffic every interval into
-classes.  Once the class is determined, the InterruptThrottleRate value is
-adjusted to suit that traffic type the best. There are three classes defined:
-"Bulk traffic", for large amounts of packets of normal size; "Low latency",
-for small amounts of traffic and/or a significant percentage of small
-packets; and "Lowest latency", for almost completely small packets or
-minimal traffic.
-
-In dynamic conservative mode, the InterruptThrottleRate value is set to 4000
-for traffic that falls in class "Bulk traffic". If traffic falls in the "Low
-latency" or "Lowest latency" class, the InterruptThrottleRate is increased
-stepwise to 20000. This default mode is suitable for most applications.
-
-For situations where low latency is vital such as cluster or
-grid computing, the algorithm can reduce latency even more when
-InterruptThrottleRate is set to mode 1. In this mode, which operates
-the same as mode 3, the InterruptThrottleRate will be increased stepwise to
-70000 for traffic in class "Lowest latency".
-
-In simplified mode the interrupt rate is based on the ratio of TX and
-RX traffic.  If the bytes per second rate is approximately equal, the
-interrupt rate will drop as low as 2000 interrupts per second.  If the
-traffic is mostly transmit or mostly receive, the interrupt rate could
-be as high as 8000.
-
-Setting InterruptThrottleRate to 0 turns off any interrupt moderation
-and may improve small packet latency, but is generally not suitable
-for bulk throughput traffic.
-
-NOTE:  InterruptThrottleRate takes precedence over the TxAbsIntDelay and
-       RxAbsIntDelay parameters.  In other words, minimizing the receive
-       and/or transmit absolute delays does not force the controller to
-       generate more interrupts than what the Interrupt Throttle Rate
-       allows.
-
-NOTE:  When e1000e is loaded with default settings and multiple adapters
-       are in use simultaneously, the CPU utilization may increase non-
-       linearly.  In order to limit the CPU utilization without impacting
-       the overall throughput, we recommend that you load the driver as
-       follows:
-
-           modprobe e1000e InterruptThrottleRate=3000,3000,3000
-
-       This sets the InterruptThrottleRate to 3000 interrupts/sec for
-       the first, second, and third instances of the driver.  The range
-       of 2000 to 3000 interrupts per second works on a majority of
-       systems and is a good starting point, but the optimal value will
-       be platform-specific.  If CPU utilization is not a concern, use
-       RX_POLLING (NAPI) and default driver settings.
-
-RxIntDelay
-----------
-Valid Range:   0-65535 (0=off)
-Default Value: 0
-
-This value delays the generation of receive interrupts in units of 1.024
-microseconds.  Receive interrupt reduction can improve CPU efficiency if
-properly tuned for specific network traffic.  Increasing this value adds
-extra latency to frame reception and can end up decreasing the throughput
-of TCP traffic.  If the system is reporting dropped receives, this value
-may be set too high, causing the driver to run out of available receive
-descriptors.
-
-CAUTION:  When setting RxIntDelay to a value other than 0, adapters may
-          hang (stop transmitting) under certain network conditions.  If
-          this occurs a NETDEV WATCHDOG message is logged in the system
-          event log.  In addition, the controller is automatically reset,
-          restoring the network connection.  To eliminate the potential
-          for the hang ensure that RxIntDelay is set to 0.
-
-RxAbsIntDelay
--------------
-Valid Range:   0-65535 (0=off)
-Default Value: 8
-
-This value, in units of 1.024 microseconds, limits the delay in which a
-receive interrupt is generated.  Useful only if RxIntDelay is non-zero,
-this value ensures that an interrupt is generated after the initial
-packet is received within the set amount of time.  Proper tuning,
-along with RxIntDelay, may improve traffic throughput in specific network
-conditions.
-
-TxIntDelay
-----------
-Valid Range:   0-65535 (0=off)
-Default Value: 8
-
-This value delays the generation of transmit interrupts in units of
-1.024 microseconds.  Transmit interrupt reduction can improve CPU
-efficiency if properly tuned for specific network traffic.  If the
-system is reporting dropped transmits, this value may be set too high
-causing the driver to run out of available transmit descriptors.
-
-TxAbsIntDelay
--------------
-Valid Range:   0-65535 (0=off)
-Default Value: 32
-
-This value, in units of 1.024 microseconds, limits the delay in which a
-transmit interrupt is generated.  Useful only if TxIntDelay is non-zero,
-this value ensures that an interrupt is generated after the initial
-packet is sent on the wire within the set amount of time.  Proper tuning,
-along with TxIntDelay, may improve traffic throughput in specific
-network conditions.
-
-Copybreak
----------
-Valid Range:   0-xxxxxxx (0=off)
-Default Value: 256
-
-Driver copies all packets below or equaling this size to a fresh RX
-buffer before handing it up the stack.
-
-This parameter is different than other parameters, in that it is a
-single (not 1,1,1 etc.) parameter applied to all driver instances and
-it is also available during runtime at
-/sys/module/e1000e/parameters/copybreak
-
-SmartPowerDownEnable
---------------------
-Valid Range: 0-1
-Default Value:  0 (disabled)
-
-Allows PHY to turn off in lower power states. The user can set this parameter
-in supported chipsets.
-
-KumeranLockLoss
----------------
-Valid Range: 0-1
-Default Value: 1 (enabled)
-
-This workaround skips resetting the PHY at shutdown for the initial
-silicon releases of ICH8 systems.
-
-IntMode
--------
-Valid Range: 0-2 (0=legacy, 1=MSI, 2=MSI-X)
-Default Value: 2
-
-Allows changing the interrupt mode at module load time, without requiring a
-recompile. If the driver load fails to enable a specific interrupt mode, the
-driver will try other interrupt modes, from least to most compatible.  The
-interrupt order is MSI-X, MSI, Legacy.  If specifying MSI (IntMode=1)
-interrupts, only MSI and Legacy will be attempted.
-
-CrcStripping
-------------
-Valid Range: 0-1
-Default Value: 1 (enabled)
-
-Strip the CRC from received packets before sending up the network stack.  If
-you have a machine with a BMC enabled but cannot receive IPMI traffic after
-loading or enabling the driver, try disabling this feature.
-
-WriteProtectNVM
----------------
-Valid Range: 0,1
-Default Value: 1
-
-If set to 1, configure the hardware to ignore all write/erase cycles to the
-GbE region in the ICHx NVM (in order to prevent accidental corruption of the
-NVM). This feature can be disabled by setting the parameter to 0 during initial
-driver load.
-NOTE: The machine must be power cycled (full off/on) when enabling NVM writes
-via setting the parameter to zero. Once the NVM has been locked (via the
-parameter at 1 when the driver loads) it cannot be unlocked except via power
-cycle.
-
-Additional Configurations
-=========================
-
-  Jumbo Frames
-  ------------
-  Jumbo Frames support is enabled by changing the MTU to a value larger than
-  the default of 1500.  Use the ifconfig command to increase the MTU size.
-  For example:
-
-       ifconfig eth<x> mtu 9000 up
-
-  This setting is not saved across reboots.
-
-  Notes:
-
-  - The maximum MTU setting for Jumbo Frames is 9216.  This value coincides
-    with the maximum Jumbo Frames size of 9234 bytes.
-
-  - Using Jumbo frames at 10 or 100 Mbps is not supported and may result in
-    poor performance or loss of link.
-
-  - Some adapters limit Jumbo Frames sized packets to a maximum of
-    4096 bytes and some adapters do not support Jumbo Frames.
-
-  - Jumbo Frames cannot be configured on an 82579-based Network device, if
-    MACSec is enabled on the system.
-
-  ethtool
-  -------
-  The driver utilizes the ethtool interface for driver configuration and
-  diagnostics, as well as displaying statistical information.  We
-  strongly recommend downloading the latest version of ethtool at:
-
-  https://kernel.org/pub/software/network/ethtool/
-
-  NOTE: When validating enable/disable tests on some parts (82578, for example)
-  you need to add a few seconds between tests when working with ethtool.
-
-  Speed and Duplex
-  ----------------
-  Speed and Duplex are configured through the ethtool* utility. For
-  instructions,  refer to the ethtool man page.
-
-  Enabling Wake on LAN* (WoL)
-  ---------------------------
-  WoL is configured through the ethtool* utility. For instructions on
-  enabling WoL with ethtool, refer to the ethtool man page.
-
-  WoL will be enabled on the system during the next shut down or reboot.
-  For this driver version, in order to enable WoL, the e1000e driver must be
-  loaded when shutting down or rebooting the system.
-
-  In most cases Wake On LAN is only supported on port A for multiple port
-  adapters. To verify if a port supports Wake on Lan run ethtool eth<X>.

+behaviour to the handling for PTR_TO_MAP_VALUE_OR_NULL->PTR_TO_MAP_VALUE, but
+it also handles reference tracking for the pointer. PTR_TO_SOCKET implicitly
+represents a reference to the corresponding 'struct sock'. To ensure that the
+reference is not leaked, it is imperative to NULL-check the reference and in
+the non-NULL case, and pass the valid reference to the socket release function.

+
+Identifying Your Adapter
+========================
+The driver in this release is compatible with devices based on the Intel(R)
+Ethernet Multi-host Controller.
+
+For information on how to identify your adapter, and for the latest Intel
+network drivers, refer to the Intel Support website:
+http://www.intel.com/support
+
+
+Flow Control
+------------
+The Intel(R) Ethernet Switch Host Interface Driver does not support Flow
+Control. It will not send pause frames. This may result in dropped frames.
+
+
+Virtual Functions (VFs)
+-----------------------
+Use sysfs to enable VFs.
+Valid Range: 0-64
+
+For example::
+
+    echo $num_vf_enabled > /sys/class/net/$dev/device/sriov_numvfs //enable VFs
+    echo 0 > /sys/class/net/$dev/device/sriov_numvfs //disable VFs
+
+NOTE: Neither the device nor the driver control how VFs are mapped into config
+space. Bus layout will vary by operating system. On operating systems that
+support it, you can check sysfs to find the mapping.
+
+NOTE: When SR-IOV mode is enabled, hardware VLAN filtering and VLAN tag
+stripping/insertion will remain enabled. Please remove the old VLAN filter
+before the new VLAN filter is added. For example::
+
+    ip link set eth0 vf 0 vlan 100	// set vlan 100 for VF 0
+    ip link set eth0 vf 0 vlan 0	// Delete vlan 100
+    ip link set eth0 vf 0 vlan 200	// set a new vlan 200 for VF 0
+
+
+Additional Features and Configurations
+======================================
+
+Jumbo Frames
+------------
+Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)
+to a value larger than the default value of 1500.
+
+Use the ifconfig command to increase the MTU size. For example, enter the
+following where <x> is the interface number::
+
+    ifconfig eth<x> mtu 9000 up
+
+Alternatively, you can use the ip command as follows::
+
+    ip link set mtu 9000 dev eth<x>
+    ip link set up dev eth<x>
+
+This setting is not saved across reboots. The setting change can be made
+permanent by adding 'MTU=9000' to the file:
+
+- For RHEL: /etc/sysconfig/network-scripts/ifcfg-eth<x>
+- For SLES: /etc/sysconfig/network/<config_file>
+
+NOTE: The maximum MTU setting for Jumbo Frames is 15342. This value coincides
+with the maximum Jumbo Frames size of 15364 bytes.
+
+NOTE: This driver will attempt to use multiple page sized buffers to receive
+each jumbo packet. This should help to avoid buffer starvation issues when
+allocating receive packets.
+
+
+Generic Receive Offload, aka GRO
+--------------------------------
+The driver supports the in-kernel software implementation of GRO. GRO has
+shown that by coalescing Rx traffic into larger chunks of data, CPU
+utilization can be significantly reduced when under large Rx load. GRO is an
+evolution of the previously-used LRO interface. GRO is able to coalesce
+other protocols besides TCP. It's also safe to use with configurations that
+are problematic for LRO, namely bridging and iSCSI.
+
+
+
+Supported ethtool Commands and Options for Filtering
+----------------------------------------------------
+-n --show-nfc
+  Retrieves the receive network flow classification configurations.
+
+rx-flow-hash tcp4|udp4|ah4|esp4|sctp4|tcp6|udp6|ah6|esp6|sctp6

+
+
+Identifying Your Adapter
+========================
+The driver is compatible with devices based on the following:
+
+ * Intel(R) Ethernet Controller X710
+ * Intel(R) Ethernet Controller XL710
+ * Intel(R) Ethernet Network Connection X722
+ * Intel(R) Ethernet Controller XXV710
+
+For the best performance, make sure the latest NVM/FW is installed on your

+For information about supported media, refer to this document:
+https://www.intel.com/content/dam/www/public/us/en/documents/release-notes/xl710-ethernet-controller-feature-matrix.pdf
+
+NOTE: Some adapters based on the Intel(R) Ethernet Controller 700 Series only
+support Intel Ethernet Optics modules. On these adapters, other modules are not
+supported and will not function.  In all cases Intel recommends using Intel
+Ethernet Optics; other modules may function but are not validated by Intel.
+Contact Intel for supported media types.
+
+NOTE: For connections based on Intel(R) Ethernet Controller 700 Series, support
+is dependent on your system board. Please see your vendor for details.
+
+NOTE: In systems that do not have adequate airflow to cool the adapter and
+optical modules, you must use high temperature optical modules.
+
+Virtual Functions (VFs)
+-----------------------
+Use sysfs to enable VFs. For example::
+
+  #echo $num_vf_enabled > /sys/class/net/$dev/device/sriov_numvfs #enable VFs
+  #echo 0 > /sys/class/net/$dev/device/sriov_numvfs #disable VFs
+
+For example, the following instructions will configure PF eth0 and the first VF
+on VLAN 10::
+
+  $ ip link set dev eth0 vf 0 vlan 10
+
+VLAN Tag Packet Steering
+------------------------
+Allows you to send all packets with a specific VLAN tag to a particular SR-IOV
+virtual function (VF). Further, this feature allows you to designate a
+particular VF as trusted, and allows that trusted VF to request selective
+promiscuous mode on the Physical Function (PF).
+
+To set a VF as trusted or untrusted, enter the following command in the
+Hypervisor::
+
+  # ip link set dev eth0 vf 1 trust [on|off]
+
+Once the VF is designated as trusted, use the following commands in the VM to
+set the VF to promiscuous mode.
+
+::
+
+  For promiscuous all:
+  #ip link set eth2 promisc on
+  Where eth2 is a VF interface in the VM
+
+  For promiscuous Multicast:
+  #ip link set eth2 allmulticast on
+  Where eth2 is a VF interface in the VM
+
+NOTE: By default, the ethtool priv-flag vf-true-promisc-support is set to
+"off",meaning that promiscuous mode for the VF will be limited. To set the
+promiscuous mode for the VF to true promiscuous and allow the VF to see all
+ingress traffic, use the following command::
+
+  #ethtool -set-priv-flags p261p1 vf-true-promisc-support on
+
+The vf-true-promisc-support priv-flag does not enable promiscuous mode; rather,
+it designates which type of promiscuous mode (limited or true) you will get
+when you enable promiscuous mode using the ip link commands above. Note that
+this is a global setting that affects the entire device. However,the
+vf-true-promisc-support priv-flag is only exposed to the first PF of the
+device. The PF remains in limited promiscuous mode (unless it is in MFP mode)
+regardless of the vf-true-promisc-support setting.
+
+Now add a VLAN interface on the VF interface::
+
+  #ip link add link eth2 name eth2.100 type vlan id 100
+
+Note that the order in which you set the VF to promiscuous mode and add the
+VLAN interface does not matter (you can do either first). The end result in
+this example is that the VF will get all traffic that is tagged with VLAN 100.
+
+Intel(R) Ethernet Flow Director
+-------------------------------
+The Intel Ethernet Flow Director performs the following tasks:
+
+- Directs receive packets according to their flows to different queues.
+- Enables tight control on routing a flow in the platform.
+- Matches flows and CPU cores for flow affinity.
+- Supports multiple parameters for flexible flow classification and load
+  balancing (in SFP mode only).
+
+NOTE: The Linux i40e driver supports the following flow types: IPv4, TCPv4, and
+UDPv4. For a given flow type, it supports valid combinations of IP addresses
+(source or destination) and UDP/TCP ports (source and destination). For
+example, you can supply only a source IP address, a source IP address and a
+destination port, or any combination of one or more of these four parameters.
+
+NOTE: The Linux i40e driver allows you to filter traffic based on a
+user-defined flexible two-byte pattern and offset by using the ethtool user-def
+and mask fields. Only L3 and L4 flow types are supported for user-defined
+flexible filters. For a given flow type, you must clear all Intel Ethernet Flow
+Director filters before changing the input set (for that flow type).
+
+To enable or disable the Intel Ethernet Flow Director::
+
+  # ethtool -K ethX ntuple <on|off>
+
+When disabling ntuple filters, all the user programmed filters are flushed from
+the driver cache and hardware. All needed filters must be re-added when ntuple
+is re-enabled.
+
+To add a filter that directs packet to queue 2, use -U or -N switch::
+
+  # ethtool -N ethX flow-type tcp4 src-ip 192.168.10.1 dst-ip \
+  192.168.10.2 src-port 2000 dst-port 2001 action 2 [loc 1]
+
+To set a filter using only the source and destination IP address::
+
+  # ethtool -N ethX flow-type tcp4 src-ip 192.168.10.1 dst-ip \
+  192.168.10.2 action 2 [loc 1]
+
+To see the list of filters currently present::
+
+  # ethtool <-u|-n> ethX
+
+Application Targeted Routing (ATR) Perfect Filters
+--------------------------------------------------
+ATR is enabled by default when the kernel is in multiple transmit queue mode.
+An ATR Intel Ethernet Flow Director filter rule is added when a TCP-IP flow
+starts and is deleted when the flow ends. When a TCP-IP Intel Ethernet Flow
+Director rule is added from ethtool (Sideband filter), ATR is turned off by the
+driver. To re-enable ATR, the sideband can be disabled with the ethtool -K
+option. For example::
+
+  ethtool –K [adapter] ntuple [off|on]
+
+If sideband is re-enabled after ATR is re-enabled, ATR remains enabled until a
+TCP-IP flow is added. When all TCP-IP sideband rules are deleted, ATR is
+automatically re-enabled.
+
+Packets that match the ATR rules are counted in fdir_atr_match stats in
+ethtool, which also can be used to verify whether ATR rules still exist.
+
+Sideband Perfect Filters
+------------------------
+Sideband Perfect Filters are used to direct traffic that matches specified
+characteristics. They are enabled through ethtool's ntuple interface. To add a
+new filter use the following command::
+
+  ethtool -U <device> flow-type <type> src-ip <ip> dst-ip <ip> src-port <port> \
+  dst-port <port> action <queue>
+
+Where:
+  <device> - the ethernet device to program
+  <type> - can be ip4, tcp4, udp4, or sctp4
+  <ip> - the ip address to match on
+  <port> - the port number to match on
+  <queue> - the queue to direct traffic towards (-1 discards matching traffic)
+
+Use the following command to display all of the active filters::
+
+  ethtool -u <device>
+
+Use the following command to delete a filter::
+
+  ethtool -U <device> delete <N>
+
+Where <N> is the filter id displayed when printing all the active filters, and
+may also have been specified using "loc <N>" when adding the filter.
+
+The following example matches TCP traffic sent from 192.168.0.1, port 5300,
+directed to 192.168.0.5, port 80, and sends it to queue 7::
+
+  ethtool -U enp130s0 flow-type tcp4 src-ip 192.168.0.1 dst-ip 192.168.0.5 \
+  src-port 5300 dst-port 80 action 7
+
+For each flow-type, the programmed filters must all have the same matching
+input set. For example, issuing the following two commands is acceptable::
+
+  ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.1 src-port 5300 action 7
+  ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.5 src-port 55 action 10
+
+Issuing the next two commands, however, is not acceptable, since the first
+specifies src-ip and the second specifies dst-ip::
+
+  ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.1 src-port 5300 action 7
+  ethtool -U enp130s0 flow-type ip4 dst-ip 192.168.0.5 src-port 55 action 10
+
+The second command will fail with an error. You may program multiple filters
+with the same fields, using different values, but, on one device, you may not
+program two tcp4 filters with different matching fields.
+
+Matching on a sub-portion of a field is not supported by the i40e driver, thus
+partial mask fields are not supported.
+
+The driver also supports matching user-defined data within the packet payload.
+This flexible data is specified using the "user-def" field of the ethtool
+command in the following way:
+
++----------------------------+--------------------------+
+| 31    28    24    20    16 | 15    12    8    4    0  |
++----------------------------+--------------------------+
+| offset into packet payload | 2 bytes of flexible data |
++----------------------------+--------------------------+
+
+For example,
+
+::
+
+  ... user-def 0x4FFFF ...
+
+tells the filter to look 4 bytes into the payload and match that value against
+0xFFFF. The offset is based on the beginning of the payload, and not the
+beginning of the packet. Thus
+
+::
+
+  flow-type tcp4 ... user-def 0x8BEAF ...
+
+would match TCP/IPv4 packets which have the value 0xBEAF 8 bytes into the
+TCP/IPv4 payload.
+
+Note that ICMP headers are parsed as 4 bytes of header and 4 bytes of payload.
+Thus to match the first byte of the payload, you must actually add 4 bytes to
+the offset. Also note that ip4 filters match both ICMP frames as well as raw
+(unknown) ip4 frames, where the payload will be the L3 payload of the IP4 frame.
+
+The maximum offset is 64. The hardware will only read up to 64 bytes of data
+from the payload. The offset must be even because the flexible data is 2 bytes
+long and must be aligned to byte 0 of the packet payload.
+
+The user-defined flexible offset is also considered part of the input set and
+cannot be programmed separately for multiple filters of the same type. However,
+the flexible data is not part of the input set and multiple filters may use the
+same offset but match against different data.
+
+To create filters that direct traffic to a specific Virtual Function, use the
+"action" parameter. Specify the action as a 64 bit value, where the lower 32
+bits represents the queue number, while the next 8 bits represent which VF.
+Note that 0 is the PF, so the VF identifier is offset by 1. For example::
+
+  ... action 0x800000002 ...
+
+specifies to direct traffic to Virtual Function 7 (8 minus 1) into queue 2 of
+that VF.
+
+Note that these filters will not break internal routing rules, and will not
+route traffic that otherwise would not have been sent to the specified Virtual
+Function.
+
+Setting the link-down-on-close Private Flag
+-------------------------------------------
+When the link-down-on-close private flag is set to "on", the port's link will
+go down when the interface is brought down using the ifconfig ethX down command.
+
+Use ethtool to view and set link-down-on-close, as follows::
+
+  ethtool --show-priv-flags ethX
+  ethtool --set-priv-flags ethX link-down-on-close [on|off]
+
+Viewing Link Messages
+---------------------
+Link messages will not be displayed to the console if the distribution is
+restricting system messages. In order to see network driver link messages on
+your console, set dmesg to eight by entering the following::
+
+  dmesg -n 8
+
+NOTE: This setting is not saved across reboots.
+
+Jumbo Frames
+------------
+Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)
+to a value larger than the default value of 1500.
+
+Use the ifconfig command to increase the MTU size. For example, enter the
+following where <x> is the interface number::
+
+  ifconfig eth<x> mtu 9000 up
+
+Alternatively, you can use the ip command as follows::
+
+  ip link set mtu 9000 dev eth<x>
+  ip link set up dev eth<x>
+
+This setting is not saved across reboots. The setting change can be made
+permanent by adding 'MTU=9000' to the file::
+
+  /etc/sysconfig/network-scripts/ifcfg-eth<x> // for RHEL
+  /etc/sysconfig/network/<config_file> // for SLES
+
+NOTE: The maximum MTU setting for Jumbo Frames is 9702. This value coincides
+with the maximum Jumbo Frames size of 9728 bytes.
+
+NOTE: This driver will attempt to use multiple page sized buffers to receive
+each jumbo packet. This should help to avoid buffer starvation issues when
+allocating receive packets.
+
+ethtool
+-------
+The driver utilizes the ethtool interface for driver configuration and
+diagnostics, as well as displaying statistical information. The latest ethtool
+version is required for this functionality. Download it at:
+https://www.kernel.org/pub/software/network/ethtool/
+
+Supported ethtool Commands and Options for Filtering
+----------------------------------------------------
+-n --show-nfc
+  Retrieves the receive network flow classification configurations.
+
+rx-flow-hash tcp4|udp4|ah4|esp4|sctp4|tcp6|udp6|ah6|esp6|sctp6
+  Retrieves the hash options for the specified network traffic type.
+
+-N --config-nfc
+  Configures the receive network flow classification.
+
+rx-flow-hash tcp4|udp4|ah4|esp4|sctp4|tcp6|udp6|ah6|esp6|sctp6 m|v|t|s|d|f|n|r...
+  Configures the hash options for the specified network traffic type.
+
+udp4 UDP over IPv4
+udp6 UDP over IPv6
+
+f Hash on bytes 0 and 1 of the Layer 4 header of the Rx packet.
+n Hash on bytes 2 and 3 of the Layer 4 header of the Rx packet.
+
+Speed and Duplex Configuration
+------------------------------
+In addressing speed and duplex configuration issues, you need to distinguish
+between copper-based adapters and fiber-based adapters.
+
+In the default mode, an Intel(R) Ethernet Network Adapter using copper
+connections will attempt to auto-negotiate with its link partner to determine
+the best setting. If the adapter cannot establish link with the link partner
+using auto-negotiation, you may need to manually configure the adapter and link
+partner to identical settings to establish link and pass packets. This should
+only be needed when attempting to link with an older switch that does not
+support auto-negotiation or one that has been forced to a specific speed or
+duplex mode. Your link partner must match the setting you choose. 1 Gbps speeds
+and higher cannot be forced. Use the autonegotiation advertising setting to
+manually set devices for 1 Gbps and higher.
+
+NOTE: You cannot set the speed for devices based on the Intel(R) Ethernet
+Network Adapter XXV710 based devices.
+
+Speed, duplex, and autonegotiation advertising are configured through the
+ethtool* utility.
+
+Caution: Only experienced network administrators should force speed and duplex
+or change autonegotiation advertising manually. The settings at the switch must
+always match the adapter settings. Adapter performance may suffer or your
+adapter may not operate if you configure the adapter differently from your
+switch.
+
+An Intel(R) Ethernet Network Adapter using fiber-based connections, however,
+will not attempt to auto-negotiate with its link partner since those adapters
+operate only in full duplex and only at their native speed.
+
+NAPI
+----
+NAPI (Rx polling mode) is supported in the i40e driver.
+For more information on NAPI, see
+https://wiki.linuxfoundation.org/networking/napi
+
+Flow Control
+------------
+Ethernet Flow Control (IEEE 802.3x) can be configured with ethtool to enable
+receiving and transmitting pause frames for i40e. When transmit is enabled,
+pause frames are generated when the receive packet buffer crosses a predefined
+threshold. When receive is enabled, the transmit unit will halt for the time
+delay specified when a pause frame is received.
+
+NOTE: You must have a flow control capable link partner.
+
+Flow Control is on by default.
+
+Use ethtool to change the flow control settings.
+
+To enable or disable Rx or Tx Flow Control::
+
+  ethtool -A eth? rx <on|off> tx <on|off>
+
+Note: This command only enables or disables Flow Control if auto-negotiation is
+disabled. If auto-negotiation is enabled, this command changes the parameters
+used for auto-negotiation with the link partner.
+
+To enable or disable auto-negotiation::
+
+  ethtool -s eth? autoneg <on|off>
+
+Note: Flow Control auto-negotiation is part of link auto-negotiation. Depending
+on your device, you may not be able to change the auto-negotiation setting.
+
+RSS Hash Flow
+-------------
+Allows you to set the hash bytes per flow type and any combination of one or
+more options for Receive Side Scaling (RSS) hash byte configuration.
+
+::
+
+  # ethtool -N <dev> rx-flow-hash <type> <option>
+
+Where <type> is:
+  tcp4	signifying TCP over IPv4
+  udp4	signifying UDP over IPv4
+  tcp6	signifying TCP over IPv6
+  udp6	signifying UDP over IPv6
+And <option> is one or more of:
+  s	Hash on the IP source address of the Rx packet.
+  d	Hash on the IP destination address of the Rx packet.
+  f	Hash on bytes 0 and 1 of the Layer 4 header of the Rx packet.
+  n	Hash on bytes 2 and 3 of the Layer 4 header of the Rx packet.
+
+MAC and VLAN anti-spoofing feature
+----------------------------------
+When a malicious driver attempts to send a spoofed packet, it is dropped by the
+hardware and not transmitted.
+NOTE: This feature can be disabled for a specific Virtual Function (VF)::
+
+  ip link set <pf dev> vf <vf id> spoofchk {off|on}
+
+IEEE 1588 Precision Time Protocol (PTP) Hardware Clock (PHC)
+------------------------------------------------------------
+Precision Time Protocol (PTP) is used to synchronize clocks in a computer
+network. PTP support varies among Intel devices that support this driver. Use
+"ethtool -T <netdev name>" to get a definitive list of PTP capabilities
+supported by the device.
+
+IEEE 802.1ad (QinQ) Support
+---------------------------
+The IEEE 802.1ad standard, informally known as QinQ, allows for multiple VLAN
+IDs within a single Ethernet frame. VLAN IDs are sometimes referred to as
+"tags," and multiple VLAN IDs are thus referred to as a "tag stack." Tag stacks
+allow L2 tunneling and the ability to segregate traffic within a particular
+VLAN ID, among other uses.
+
+The following are examples of how to configure 802.1ad (QinQ)::
+
+  ip link add link eth0 eth0.24 type vlan proto 802.1ad id 24
+  ip link add link eth0.24 eth0.24.371 type vlan proto 802.1Q id 371
+
+Where "24" and "371" are example VLAN IDs.
+
+NOTES:
+  Receive checksum offloads, cloud filters, and VLAN acceleration are not
+  supported for 802.1ad (QinQ) packets.
+
+VXLAN and GENEVE Overlay HW Offloading
+--------------------------------------
+Virtual Extensible LAN (VXLAN) allows you to extend an L2 network over an L3
+network, which may be useful in a virtualized or cloud environment. Some
+Intel(R) Ethernet Network devices perform VXLAN processing, offloading it from
+the operating system. This reduces CPU utilization.
+
+VXLAN offloading is controlled by the Tx and Rx checksum offload options
+provided by ethtool. That is, if Tx checksum offload is enabled, and the
+adapter has the capability, VXLAN offloading is also enabled.
+
+Support for VXLAN and GENEVE HW offloading is dependent on kernel support of
+the HW offloading features.
+
+Multiple Functions per Port
+---------------------------
+Some adapters based on the Intel Ethernet Controller X710/XL710 support
+multiple functions on a single physical port. Configure these functions through
+the System Setup/BIOS.
+
+Minimum TX Bandwidth is the guaranteed minimum data transmission bandwidth, as
+a percentage of the full physical port link speed, that the partition will
+receive. The bandwidth the partition is awarded will never fall below the level
+you specify.
+
+The range for the minimum bandwidth values is:
+1 to ((100 minus # of partitions on the physical port) plus 1)
+For example, if a physical port has 4 partitions, the range would be:
+1 to ((100 - 4) + 1 = 97)
+
+The Maximum Bandwidth percentage represents the maximum transmit bandwidth
+allocated to the partition as a percentage of the full physical port link
+speed. The accepted range of values is 1-100. The value is used as a limiter,
+should you chose that any one particular function not be able to consume 100%
+of a port's bandwidth (should it be available). The sum of all the values for
+Maximum Bandwidth is not restricted, because no more than 100% of a port's
+bandwidth can ever be used.
+
+NOTE: X710/XXV710 devices fail to enable Max VFs (64) when Multiple Functions
+per Port (MFP) and SR-IOV are enabled. An error from i40e is logged that says
+"add vsi failed for VF N, aq_err 16". To workaround the issue, enable less than
+64 virtual functions (VFs).
+
+Data Center Bridging (DCB)
+--------------------------
+DCB is a configuration Quality of Service implementation in hardware. It uses
+the VLAN priority tag (802.1p) to filter traffic. That means that there are 8
+different priorities that traffic can be filtered into. It also enables
+priority flow control (802.1Qbb) which can limit or eliminate the number of
+dropped packets during network stress. Bandwidth can be allocated to each of
+these priorities, which is enforced at the hardware level (802.1Qaz).
+
+Adapter firmware implements LLDP and DCBX protocol agents as per 802.1AB and
+802.1Qaz respectively. The firmware based DCBX agent runs in willing mode only
+and can accept settings from a DCBX capable peer. Software configuration of
+DCBX parameters via dcbtool/lldptool are not supported.
+
+NOTE: Firmware LLDP can be disabled by setting the private flag disable-fw-lldp.
+
+The i40e driver implements the DCB netlink interface layer to allow user-space
+to communicate with the driver and query DCB configuration for the port.
+
+NOTE:
+The kernel assumes that TC0 is available, and will disable Priority Flow
+Control (PFC) on the device if TC0 is not available. To fix this, ensure TC0 is
+enabled when setting up DCB on your switch.
+
+Interrupt Rate Limiting
+-----------------------
+:Valid Range: 0-235 (0=no limit)
+
+The Intel(R) Ethernet Controller XL710 family supports an interrupt rate
+limiting mechanism. The user can control, via ethtool, the number of
+microseconds between interrupts.
+
+Syntax::
+
+  # ethtool -C ethX rx-usecs-high N
+
+The range of 0-235 microseconds provides an effective range of 4,310 to 250,000
+interrupts per second. The value of rx-usecs-high can be set independently of
+rx-usecs and tx-usecs in the same ethtool command, and is also independent of
+the adaptive interrupt moderation algorithm. The underlying hardware supports
+granularity in 4-microsecond intervals, so adjacent values may result in the
+same interrupt rate.
+
+One possible use case is the following::
+
+  # ethtool -C ethX adaptive-rx off adaptive-tx off rx-usecs-high 20 rx-usecs \
+    5 tx-usecs 5
+
+The above command would disable adaptive interrupt moderation, and allow a
+maximum of 5 microseconds before indicating a receive or transmit was complete.
+However, instead of resulting in as many as 200,000 interrupts per second, it
+limits total interrupts per second to 50,000 via the rx-usecs-high parameter.
+
+Performance Optimization
+========================
+Driver defaults are meant to fit a wide variety of workloads, but if further
+optimization is required we recommend experimenting with the following settings.
+
+NOTE: For better performance when processing small (64B) frame sizes, try
+enabling Hyper threading in the BIOS in order to increase the number of logical
+cores in the system and subsequently increase the number of queues available to
+the adapter.
+
+Virtualized Environments
+------------------------
+1. Disable XPS on both ends by using the included virt_perf_default script
+or by running the following command as root::
+
+  for file in `ls /sys/class/net/<ethX>/queues/tx-*/xps_cpus`;
+  do echo 0 > $file; done
+
+2. Using the appropriate mechanism (vcpupin) in the vm, pin the cpu's to
+individual lcpu's, making sure to use a set of cpu's included in the
+device's local_cpulist: /sys/class/net/<ethX>/device/local_cpulist.
+
+3. Configure as many Rx/Tx queues in the VM as available. Do not rely on
+the default setting of 1.
+
+
+Non-virtualized Environments
+----------------------------
+Pin the adapter's IRQs to specific cores by disabling the irqbalance service
+and using the included set_irq_affinity script. Please see the script's help
+text for further options.
+
+- The following settings will distribute the IRQs across all the cores evenly::
+
+  # scripts/set_irq_affinity -x all <interface1> , [ <interface2>, ... ]
+
+- The following settings will distribute the IRQs across all the cores that are
+  local to the adapter (same NUMA node)::
+
+  # scripts/set_irq_affinity -x local <interface1> ,[ <interface2>, ... ]
+
+For very CPU intensive workloads, we recommend pinning the IRQs to all cores.
+
+For IP Forwarding: Disable Adaptive ITR and lower Rx and Tx interrupts per
+queue using ethtool.
+
+- Setting rx-usecs and tx-usecs to 125 will limit interrupts to about 8000
+  interrupts per second per queue.
+
+::
+
+  # ethtool -C <interface> adaptive-rx off adaptive-tx off rx-usecs 125 \
+    tx-usecs 125
+
+For lower CPU utilization: Disable Adaptive ITR and lower Rx and Tx interrupts
+per queue using ethtool.
+
+- Setting rx-usecs and tx-usecs to 250 will limit interrupts to about 4000
+  interrupts per second per queue.
+
+::
+
+  # ethtool -C <interface> adaptive-rx off adaptive-tx off rx-usecs 250 \
+    tx-usecs 250
+
+For lower latency: Disable Adaptive ITR and ITR by setting Rx and Tx to 0 using
+ethtool.
+
+::
+
+  # ethtool -C <interface> adaptive-rx off adaptive-tx off rx-usecs 0 \
+    tx-usecs 0
+
+Application Device Queues (ADq)
+-------------------------------
+Application Device Queues (ADq) allows you to dedicate one or more queues to a
+specific application. This can reduce latency for the specified application,
+and allow Tx traffic to be rate limited per application. Follow the steps below
+to set ADq.
+
+1. Create traffic classes (TCs). Maximum of 8 TCs can be created per interface.
+The shaper bw_rlimit parameter is optional.
+
+Example: Sets up two tcs, tc0 and tc1, with 16 queues each and max tx rate set
+to 1Gbit for tc0 and 3Gbit for tc1.
+
+::
+
+  # tc qdisc add dev <interface> root mqprio num_tc 2 map 0 0 0 0 1 1 1 1
+  queues 16@0 16@16 hw 1 mode channel shaper bw_rlimit min_rate 1Gbit 2Gbit
+  max_rate 1Gbit 3Gbit
+
+map: priority mapping for up to 16 priorities to tcs (e.g. map 0 0 0 0 1 1 1 1
+sets priorities 0-3 to use tc0 and 4-7 to use tc1)
+
+queues: for each tc, <num queues>@<offset> (e.g. queues 16@0 16@16 assigns
+16 queues to tc0 at offset 0 and 16 queues to tc1 at offset 16. Max total
+number of queues for all tcs is 64 or number of cores, whichever is lower.)
+
+hw 1 mode channel: ‘channel’ with ‘hw’ set to 1 is a new new hardware
+offload mode in mqprio that makes full use of the mqprio options, the
+TCs, the queue configurations, and the QoS parameters.
+
+shaper bw_rlimit: for each tc, sets minimum and maximum bandwidth rates.
+Totals must be equal or less than port speed.
+
+For example: min_rate 1Gbit 3Gbit: Verify bandwidth limit using network
+monitoring tools such as ifstat or sar –n DEV [interval] [number of samples]
+
+2. Enable HW TC offload on interface::
+
+    # ethtool -K <interface> hw-tc-offload on
+
+3. Apply TCs to ingress (RX) flow of interface::
+
+    # tc qdisc add dev <interface> ingress
+
+NOTES:
+ - Run all tc commands from the iproute2 <pathtoiproute2>/tc/ directory.
+ - ADq is not compatible with cloud filters.
+ - Setting up channels via ethtool (ethtool -L) is not supported when the
+   TCs are configured using mqprio.
+ - You must have iproute2 latest version
+ - NVM version 6.01 or later is required.
+ - ADq cannot be enabled when any the following features are enabled: Data
+   Center Bridging (DCB), Multiple Functions per Port (MFP), or Sideband
+   Filters.
+ - If another driver (for example, DPDK) has set cloud filters, you cannot
+   enable ADq.
+ - Tunnel filters are not supported in ADq. If encapsulated packets do
+   arrive in non-tunnel mode, filtering will be done on the inner headers.
+   For example, for VXLAN traffic in non-tunnel mode, PCTYPE is identified
+   as a VXLAN encapsulated packet, outer headers are ignored. Therefore,
+   inner headers are matched.
+ - If a TC filter on a PF matches traffic over a VF (on the PF), that
+   traffic will be routed to the appropriate queue of the PF, and will
+   not be passed on the VF. Such traffic will end up getting dropped higher
+   up in the TCP/IP stack as it does not match PF address data.
+ - If traffic matches multiple TC filters that point to different TCs,
+   that traffic will be duplicated and sent to all matching TC queues.
+   The hardware switch mirrors the packet to a VSI list when multiple
+   filters are matched.
+
+
+Known Issues/Troubleshooting
+============================
+
+NOTE: 1 Gb devices based on the Intel(R) Ethernet Network Connection X722 do
+not support the following features:
+
+  * Data Center Bridging (DCB)
+  * QOS
+  * VMQ
+  * SR-IOV
+  * Task Encapsulation offload (VXLAN, NVGRE)
+  * Energy Efficient Ethernet (EEE)
+  * Auto-media detect
+
+Unexpected Issues when the device driver and DPDK share a device
+----------------------------------------------------------------
+Unexpected issues may result when an i40e device is in multi driver mode and
+the kernel driver and DPDK driver are sharing the device. This is because
+access to the global NIC resources is not synchronized between multiple
+drivers. Any change to the global NIC configuration (writing to a global
+register, setting global configuration by AQ, or changing switch modes) will
+affect all ports and drivers on the device. Loading DPDK with the
+"multi-driver" module parameter may mitigate some of the issues.
+
+TC0 must be enabled when setting up DCB on a switch
+---------------------------------------------------
+The kernel assumes that TC0 is available, and will disable Priority Flow
+Control (PFC) on the device if TC0 is not available. To fix this, ensure TC0 is
+enabled when setting up DCB on your switch.

-Identifying Your Adapter
-========================
-
-The driver in this release is compatible with the Intel Ethernet
-Controller XL710 Family.
-
-For more information on how to identify your adapter, go to the Adapter &
-Driver ID Guide at:
-
-    http://support.intel.com/support/network/sb/CS-012904.htm
-
-
-Enabling the driver
-===================
-
-The driver is enabled via the standard kernel configuration system,
-using the make command:
-
-     make config/oldconfig/menuconfig/etc.
-
-The driver is located in the menu structure at:
-
-	-> Device Drivers
-	  -> Network device support (NETDEVICES [=y])
-	    -> Ethernet driver support
-	      -> Intel devices
-	        -> Intel(R) Ethernet Controller XL710 Family
-
-Additional Configurations
-=========================
-
-  Generic Receive Offload (GRO)
-  -----------------------------
-  The driver supports the in-kernel software implementation of GRO.  GRO has
-  shown that by coalescing Rx traffic into larger chunks of data, CPU
-  utilization can be significantly reduced when under large Rx load.  GRO is
-  an evolution of the previously-used LRO interface.  GRO is able to coalesce
-  other protocols besides TCP.  It's also safe to use with configurations that
-  are problematic for LRO, namely bridging and iSCSI.
-
-  Ethtool
-  -------
-  The driver utilizes the ethtool interface for driver configuration and
-  diagnostics, as well as displaying statistical information. The latest
-  ethtool version is required for this functionality.
-
-  The latest release of ethtool can be found from
-  https://www.kernel.org/pub/software/network/ethtool
-
-
-  Flow Director n-ntuple traffic filters (FDir)
-  ---------------------------------------------
-  The driver utilizes the ethtool interface for configuring ntuple filters,
-  via "ethtool -N <device> <filter>".
-
-  The sctp4, ip4, udp4, and tcp4 flow types are supported with the standard
-  fields including src-ip, dst-ip, src-port and dst-port. The driver only
-  supports fully enabling or fully masking the fields, so use of the mask
-  fields for partial matches is not supported.
-
-  Additionally, the driver supports using the action to specify filters for a
-  Virtual Function. You can specify the action as a 64bit value, where the
-  lower 32 bits represents the queue number, while the next 8 bits represent
-  which VF. Note that 0 is the PF, so the VF identifier is offset by 1. For
-  example:
-
-    ... action 0x800000002 ...
-
-  Would indicate to direct traffic for Virtual Function 7 (8 minus 1) on queue
-  2 of that VF.
-
-  The driver also supports using the user-defined field to specify 2 bytes of
-  arbitrary data to match within the packet payload in addition to the regular
-  fields. The data is specified in the lower 32bits of the user-def field in
-  the following way:
-
-  +----------------------------+---------------------------+
-  | 31    28    24    20    16 | 15    12     8     4     0|
-  +----------------------------+---------------------------+
-  | offset into packet payload |  2 bytes of flexible data |
-  +----------------------------+---------------------------+
-
-  As an example,
-
-    ... user-def 0x4FFFF ....
-
-  means to match the value 0xFFFF 4 bytes into the packet payload. Note that
-  the offset is based on the beginning of the payload, and not the beginning
-  of the packet. Thus
-
-    flow-type tcp4 ... user-def 0x8BEAF ....
-
-  would match TCP/IPv4 packets which have the value 0xBEAF 8bytes into the
-  TCP/IPv4 payload.
-
-  For ICMP, the hardware parses the ICMP header as 4 bytes of header and 4
-  bytes of payload, so if you want to match an ICMP frames payload you may need
-  to add 4 to the offset in order to match the data.
-
-  Furthermore, the offset can only be up to a value of 64, as the hardware
-  will only read up to 64 bytes of data from the payload. It must also be even
-  as the flexible data is 2 bytes long and must be aligned to byte 0 of the
-  packet payload.
-
-  When programming filters, the hardware is limited to using a single input
-  set for each flow type. This means that it is an error to program two
-  different filters with the same type that don't match on the same fields.
-  Thus the second of the following two commands will fail:
-
-    ethtool -N <device> flow-type tcp4 src-ip 192.168.0.7 action 5
-    ethtool -N <device> flow-type tcp4 dst-ip 192.168.15.18 action 1
-
-  This is because the first filter will be accepted and reprogram the input
-  set for TCPv4 filters, but the second filter will be unable to reprogram the
-  input set until all the conflicting TCPv4 filters are first removed.
-
-  Note that the user-defined flexible offset is also considered part of the
-  input set and cannot be programmed separately for multiple filters of the
-  same type. However, the flexible data is not part of the input set and
-  multiple filters may use the same offset but match against different data.
-
-  Data Center Bridging (DCB)
-  --------------------------
-  DCB configuration is not currently supported.
-
-  FCoE
-  ----
-  The driver supports Fiber Channel over Ethernet (FCoE) and Data Center
-  Bridging (DCB) functionality. Configuring DCB and FCoE is outside the scope
-  of this driver doc. Refer to http://www.open-fcoe.org/ for FCoE project
-  information and http://www.open-lldp.org/ or email list
-  e1000-eedc@lists.sourceforge.net for DCB information.
-
-  MAC and VLAN anti-spoofing feature
-  ----------------------------------
-  When a malicious driver attempts to send a spoofed packet, it is dropped by
-  the hardware and not transmitted.  An interrupt is sent to the PF driver
-  notifying it of the spoof attempt.
-
-  When a spoofed packet is detected the PF driver will send the following
-  message to the system log (displayed by  the "dmesg" command):
-
-  Spoof event(s) detected on VF (n)
-
-  Where n=the VF that attempted to do the spoofing.

+diagnostics, as well as displaying statistical information. The latest ethtool
+version is required for this functionality. Download it at:
+https://www.kernel.org/pub/software/network/ethtool/
+
+Setting VLAN Tag Stripping
+--------------------------
+If you have applications that require Virtual Functions (VFs) to receive
+packets with VLAN tags, you can disable VLAN tag stripping for the VF. The
+Physical Function (PF) processes requests issued from the VF to enable or
+disable VLAN tag stripping. Note that if the PF has assigned a VLAN to a VF,
+then requests from that VF to set VLAN tag stripping will be ignored.
+
+To enable/disable VLAN tag stripping for a VF, issue the following command
+from inside the VM in which you are running the VF::
+
+  ethtool -K <if_name> rxvlan on/off
+
+or alternatively::
+
+  ethtool --offload <if_name> rxvlan on/off
+
+Adaptive Virtual Function
+-------------------------
+Adaptive Virtual Function (AVF) allows the virtual function driver, or VF, to
+adapt to changing feature sets of the physical function driver (PF) with which
+it is associated. This allows system administrators to update a PF without
+having to update all the VFs associated with it. All AVFs have a single common
+device ID and branding string.
+
+AVFs have a minimum set of features known as "base mode," but may provide
+additional features depending on what features are available in the PF with
+which the AVF is associated. The following are base mode features:
+
+- 4 Queue Pairs (QP) and associated Configuration Status Registers (CSRs)
+  for Tx/Rx.
+- i40e descriptors and ring format.
+- Descriptor write-back completion.
+- 1 control queue, with i40e descriptors, CSRs and ring format.
+- 5 MSI-X interrupt vectors and corresponding i40e CSRs.
+- 1 Interrupt Throttle Rate (ITR) index.
+- 1 Virtual Station Interface (VSI) per VF.
+- 1 Traffic Class (TC), TC0
+- Receive Side Scaling (RSS) with 64 entry indirection table and key,
+  configured through the PF.
+- 1 unicast MAC address reserved per VF.
+- 16 MAC address filters for each VF.
+- Stateless offloads - non-tunneled checksums.
+- AVF device ID.
+- HW mailbox is used for VF to PF communications (including on Windows).
+
+IEEE 802.1ad (QinQ) Support
+---------------------------
+The IEEE 802.1ad standard, informally known as QinQ, allows for multiple VLAN
+IDs within a single Ethernet frame. VLAN IDs are sometimes referred to as
+"tags," and multiple VLAN IDs are thus referred to as a "tag stack." Tag stacks
+allow L2 tunneling and the ability to segregate traffic within a particular
+VLAN ID, among other uses.
+
+The following are examples of how to configure 802.1ad (QinQ)::
+
+  ip link add link eth0 eth0.24 type vlan proto 802.1ad id 24
+  ip link add link eth0.24 eth0.24.371 type vlan proto 802.1Q id 371
+
+Where "24" and "371" are example VLAN IDs.
+
+NOTES:
+  Receive checksum offloads, cloud filters, and VLAN acceleration are not
+  supported for 802.1ad (QinQ) packets.
+
+Application Device Queues (ADq)
+-------------------------------
+Application Device Queues (ADq) allows you to dedicate one or more queues to a
+specific application. This can reduce latency for the specified application,
+and allow Tx traffic to be rate limited per application. Follow the steps below
+to set ADq.
+
+1. Create traffic classes (TCs). Maximum of 8 TCs can be created per interface.
+The shaper bw_rlimit parameter is optional.
+
+Example: Sets up two tcs, tc0 and tc1, with 16 queues each and max tx rate set
+to 1Gbit for tc0 and 3Gbit for tc1.
+
+::
+
+  # tc qdisc add dev <interface> root mqprio num_tc 2 map 0 0 0 0 1 1 1 1
+  queues 16@0 16@16 hw 1 mode channel shaper bw_rlimit min_rate 1Gbit 2Gbit
+  max_rate 1Gbit 3Gbit
+
+map: priority mapping for up to 16 priorities to tcs (e.g. map 0 0 0 0 1 1 1 1
+sets priorities 0-3 to use tc0 and 4-7 to use tc1)
+
+queues: for each tc, <num queues>@<offset> (e.g. queues 16@0 16@16 assigns
+16 queues to tc0 at offset 0 and 16 queues to tc1 at offset 16. Max total
+number of queues for all tcs is 64 or number of cores, whichever is lower.)
+
+hw 1 mode channel: ‘channel’ with ‘hw’ set to 1 is a new new hardware
+offload mode in mqprio that makes full use of the mqprio options, the
+TCs, the queue configurations, and the QoS parameters.
+
+shaper bw_rlimit: for each tc, sets minimum and maximum bandwidth rates.
+Totals must be equal or less than port speed.
+
+For example: min_rate 1Gbit 3Gbit: Verify bandwidth limit using network
+monitoring tools such as ifstat or sar –n DEV [interval] [number of samples]
+
+2. Enable HW TC offload on interface::
+
+    # ethtool -K <interface> hw-tc-offload on
+
+3. Apply TCs to ingress (RX) flow of interface::
+
+    # tc qdisc add dev <interface> ingress
+
+NOTES:
+ - Run all tc commands from the iproute2 <pathtoiproute2>/tc/ directory.
+ - ADq is not compatible with cloud filters.
+ - Setting up channels via ethtool (ethtool -L) is not supported when the TCs
+   are configured using mqprio.
+ - You must have iproute2 latest version
+ - NVM version 6.01 or later is required.
+ - ADq cannot be enabled when any the following features are enabled: Data
+   Center Bridging (DCB), Multiple Functions per Port (MFP), or Sideband Filters.
+ - If another driver (for example, DPDK) has set cloud filters, you cannot
+   enable ADq.
+ - Tunnel filters are not supported in ADq. If encapsulated packets do arrive
+   in non-tunnel mode, filtering will be done on the inner headers.  For example,
+   for VXLAN traffic in non-tunnel mode, PCTYPE is identified as a VXLAN
+   encapsulated packet, outer headers are ignored. Therefore, inner headers are
+   matched.
+ - If a TC filter on a PF matches traffic over a VF (on the PF), that traffic
+   will be routed to the appropriate queue of the PF, and will not be passed on
+   the VF. Such traffic will end up getting dropped higher up in the TCP/IP
+   stack as it does not match PF address data.
+ - If traffic matches multiple TC filters that point to different TCs, that
+   traffic will be duplicated and sent to all matching TC queues.  The hardware
+   switch mirrors the packet to a VSI list when multiple filters are matched.
+
+
+Known Issues/Troubleshooting
+============================
+
+Traffic Is Not Being Passed Between VM and Client
+-------------------------------------------------
+You may not be able to pass traffic between a client system and a
+Virtual Machine (VM) running on a separate host if the Virtual Function
+(VF, or Virtual NIC) is not in trusted mode and spoof checking is enabled
+on the VF. Note that this situation can occur in any combination of client,
+host, and guest operating system. For information on how to set the VF to
+trusted mode, refer to the section "VLAN Tag Packet Steering" in this
+readme document. For information on setting spoof checking, refer to the
+section "MAC and VLAN anti-spoofing feature" in this readme document.
+
+Do not unload port driver if VF with active VM is bound to it
+-------------------------------------------------------------
+Do not unload a port's driver if a Virtual Function (VF) with an active Virtual
+Machine (VM) is bound to it. Doing so will cause the port to appear to hang.
+Once the VM shuts down, or otherwise releases the VF, the command will complete.
+
+Virtual machine does not get link
+---------------------------------
+If the virtual machine has more than one virtual port assigned to it, and those
+virtual ports are bound to different physical ports, you may not get link on
+all of the virtual ports. The following command may work around the issue::
+
+  ethtool -r <PF>
+
+Where <PF> is the PF interface in the host, for example: p5p1. You may need to
+run the command more than once to get link on all virtual ports.
+
+MAC address of Virtual Function changes unexpectedly
+----------------------------------------------------
+If a Virtual Function's MAC address is not assigned in the host, then the VF
+(virtual function) driver will use a random MAC address. This random MAC
+address may change each time the VF driver is reloaded. You can assign a static
+MAC address in the host machine. This static MAC address will survive
+a VF driver reload.
+
+Driver Buffer Overflow Fix
+--------------------------
+The fix to resolve CVE-2016-8105, referenced in Intel SA-00069
+https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00069.html
+is included in this and future versions of the driver.
+
+Multiple Interfaces on Same Ethernet Broadcast Network
+------------------------------------------------------
+Due to the default ARP behavior on Linux, it is not possible to have one system
+on two IP networks in the same Ethernet broadcast domain (non-partitioned
+switch) behave as expected. All Ethernet interfaces will respond to IP traffic
+for any IP address assigned to the system. This results in unbalanced receive
+traffic.
+
+If you have multiple interfaces in a server, either turn on ARP filtering by
+entering::
+
+  echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter
+
+NOTE: This setting is not saved across reboots. The configuration change can be
+made permanent by adding the following line to the file /etc/sysctl.conf::
+
+  net.ipv4.conf.all.arp_filter = 1
+
+Another alternative is to install the interfaces in separate broadcast domains
+(either in different switches or in a switch partitioned to VLANs).
+
+Rx Page Allocation Errors
+-------------------------
+'Page allocation failure. order:0' errors may occur under stress.
+This is caused by the way the Linux kernel reports this stressed condition.

+Identifying Your Adapter
+========================
+For information on how to identify your adapter, and for the latest Intel
+network drivers, refer to the Intel Support website:
+http://www.intel.com/support
+
+
+Command Line Parameters
+========================
+If the driver is built as a module, the following optional parameters are used
+by entering them on the command line with the modprobe command using this
+syntax::
+
+    modprobe igb [<option>=<VAL1>,<VAL2>,...]
+
+There needs to be a <VAL#> for each network port in the system supported by
+this driver. The values will be applied to each instance, in function order.
+For example::
+
+    modprobe igb max_vfs=2,4
+
+In this case, there are two network ports supported by igb in the system.
+
+NOTE: A descriptor describes a data buffer and attributes related to the data
+buffer. This information is accessed by the hardware.
+
+max_vfs
+-------
+:Valid Range: 0-7
+
+This parameter adds support for SR-IOV. It causes the driver to spawn up to
+max_vfs worth of virtual functions.  If the value is greater than 0 it will
+also force the VMDq parameter to be 1 or more.
+
+The parameters for the driver are referenced by position. Thus, if you have a
+dual port adapter, or more than one adapter in your system, and want N virtual
+functions per port, you must specify a number for each port with each parameter
+separated by a comma. For example::
+
+    modprobe igb max_vfs=4
+
+This will spawn 4 VFs on the first port.
+
+::
+
+    modprobe igb max_vfs=2,4
+
+This will spawn 2 VFs on the first port and 4 VFs on the second port.
+
+NOTE: Caution must be used in loading the driver with these parameters.
+Depending on your system configuration, number of slots, etc., it is impossible
+to predict in all cases where the positions would be on the command line.
+
+NOTE: Neither the device nor the driver control how VFs are mapped into config
+space. Bus layout will vary by operating system. On operating systems that
+support it, you can check sysfs to find the mapping.
+
+NOTE: When either SR-IOV mode or VMDq mode is enabled, hardware VLAN filtering
+and VLAN tag stripping/insertion will remain enabled. Please remove the old
+VLAN filter before the new VLAN filter is added. For example::
+
+    ip link set eth0 vf 0 vlan 100	// set vlan 100 for VF 0
+    ip link set eth0 vf 0 vlan 0	// Delete vlan 100
+    ip link set eth0 vf 0 vlan 200	// set a new vlan 200 for VF 0
+
+Debug
+-----
+:Valid Range: 0-16 (0=none,...,16=all)
+:Default Value: 0
+
+This parameter adjusts the level debug messages displayed in the system logs.
+
+
+Additional Features and Configurations
+======================================
+
+Jumbo Frames
+------------
+Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)
+to a value larger than the default value of 1500.
+
+Use the ifconfig command to increase the MTU size. For example, enter the
+following where <x> is the interface number::
+
+    ifconfig eth<x> mtu 9000 up
+
+Alternatively, you can use the ip command as follows::
+
+    ip link set mtu 9000 dev eth<x>
+    ip link set up dev eth<x>
+
+This setting is not saved across reboots. The setting change can be made
+permanent by adding 'MTU=9000' to the file:
+
+- For RHEL: /etc/sysconfig/network-scripts/ifcfg-eth<x>
+- For SLES: /etc/sysconfig/network/<config_file>
+
+NOTE: The maximum MTU setting for Jumbo Frames is 9216. This value coincides
+with the maximum Jumbo Frames size of 9234 bytes.
+
+NOTE: Using Jumbo frames at 10 or 100 Mbps is not supported and may result in
+poor performance or loss of link.
+
+
+ethtool
+-------
+The driver utilizes the ethtool interface for driver configuration and
+diagnostics, as well as displaying statistical information. The latest ethtool
+version is required for this functionality. Download it at:
+
+https://www.kernel.org/pub/software/network/ethtool/
+
+
+Enabling Wake on LAN* (WoL)
+---------------------------
+WoL is configured through the ethtool* utility.
+
+WoL will be enabled on the system during the next shut down or reboot. For
+this driver version, in order to enable WoL, the igb driver must be loaded
+prior to shutting down or suspending the system.
+
+NOTE: Wake on LAN is only supported on port A of multi-port devices.  Also
+Wake On LAN is not supported for the following device:
+- Intel(R) Gigabit VT Quad Port Server Adapter
+
+
+Multiqueue
+----------
+In this mode, a separate MSI-X vector is allocated for each queue and one for
+"other" interrupts such as link status change and errors. All interrupts are
+throttled via interrupt moderation. Interrupt moderation must be used to avoid
+interrupt storms while the driver is processing one interrupt. The moderation
+value should be at least as large as the expected time for the driver to
+process an interrupt. Multiqueue is off by default.
+
+REQUIREMENTS: MSI-X support is required for Multiqueue. If MSI-X is not found,
+the system will fallback to MSI or to Legacy interrupts. This driver supports
+receive multiqueue on all kernels that support MSI-X.
+
+NOTE: On some kernels a reboot is required to switch between single queue mode
+and multiqueue mode or vice-versa.
+
+
+MAC and VLAN anti-spoofing feature
+----------------------------------
+When a malicious driver attempts to send a spoofed packet, it is dropped by the
+hardware and not transmitted.
+
+An interrupt is sent to the PF driver notifying it of the spoof attempt. When a
+spoofed packet is detected, the PF driver will send the following message to
+the system log (displayed by the "dmesg" command):
+Spoof event(s) detected on VF(n), where n = the VF that attempted to do the
+spoofing
+
+
+Setting MAC Address, VLAN and Rate Limit Using IProute2 Tool
+------------------------------------------------------------
+You can set a MAC address of a Virtual Function (VF), a default VLAN and the
+rate limit using the IProute2 tool. Download the latest version of the
+IProute2 tool from Sourceforge if your version does not have all the features
+you require.

+
+The following Intel network adapters are compatible with the drivers in this
+release:
+
++------------+------------------------------+----------------------------------+
+| Controller | Adapter Name                 | Physical Layer                   |
++============+==============================+==================================+
+| 82597EX    | Intel(R) PRO/10GbE LR/SR/CX4 | - 10G Base-LR (fiber)            |

++------------+------------------------------+----------------------------------+
+
+For more information on how to identify your adapter, go to the Adapter &
+Driver ID Guide at:
+
+    https://support.intel.com
+
+
+Command Line Parameters
+=======================
+
+If the driver is built as a module, the  following optional parameters are
+used by entering them on the command line with the modprobe command using
+this syntax::
+
+    modprobe ixgb [<option>=<VAL1>,<VAL2>,...]
+
+For example, with two 10GbE PCI adapters, entering::
+
+    modprobe ixgb TxDescriptors=80,128
+
+loads the ixgb driver with 80 TX resources for the first adapter and 128 TX
+resources for the second adapter.
+
+The default value for each parameter is generally the recommended setting,
+unless otherwise noted.
+
+Copybreak
+---------
+:Valid Range: 0-XXXX
+:Default Value: 256
+
+    This is the maximum size of packet that is copied to a new buffer on
+    receive.
+
+Debug
+-----
+:Valid Range: 0-16 (0=none,...,16=all)
+:Default Value: 0
+
+    This parameter adjusts the level of debug messages displayed in the
+    system logs.
+
+FlowControl
+-----------
+:Valid Range: 0-3 (0=none, 1=Rx only, 2=Tx only, 3=Rx&Tx)
+:Default Value: 1 if no EEPROM, otherwise read from EEPROM
+
+    This parameter controls the automatic generation(Tx) and response(Rx) to
+    Ethernet PAUSE frames.  There are hardware bugs associated with enabling
+    Tx flow control so beware.
+
+RxDescriptors
+-------------
+:Valid Range: 64-4096
+:Default Value: 1024
+
+    This value is the number of receive descriptors allocated by the driver.
+    Increasing this value allows the driver to buffer more incoming packets.
+    Each descriptor is 16 bytes.  A receive buffer is also allocated for
+    each descriptor and can be either 2048, 4056, 8192, or 16384 bytes,
+    depending on the MTU setting.  When the MTU size is 1500 or less, the
+    receive buffer size is 2048 bytes. When the MTU is greater than 1500 the
+    receive buffer size will be either 4056, 8192, or 16384 bytes.  The
+    maximum MTU size is 16114.
+
+TxDescriptors
+-------------
+:Valid Range: 64-4096
+:Default Value: 256
+
+    This value is the number of transmit descriptors allocated by the driver.
+    Increasing this value allows the driver to queue more transmits.  Each
+    descriptor is 16 bytes.
+
+RxIntDelay
+----------
+:Valid Range: 0-65535 (0=off)
+:Default Value: 72
+
+    This value delays the generation of receive interrupts in units of
+    0.8192 microseconds.  Receive interrupt reduction can improve CPU
+    efficiency if properly tuned for specific network traffic.  Increasing
+    this value adds extra latency to frame reception and can end up
+    decreasing the throughput of TCP traffic.  If the system is reporting
+    dropped receives, this value may be set too high, causing the driver to
+    run out of available receive descriptors.
+
+TxIntDelay
+----------
+:Valid Range: 0-65535 (0=off)
+:Default Value: 32
+
+    This value delays the generation of transmit interrupts in units of
+    0.8192 microseconds.  Transmit interrupt reduction can improve CPU
+    efficiency if properly tuned for specific network traffic.  Increasing
+    this value adds extra latency to frame transmission and can end up
+    decreasing the throughput of TCP traffic.  If this value is set too high,
+    it will cause the driver to run out of available transmit descriptors.
+
+XsumRX
+------
+:Valid Range: 0-1
+:Default Value: 1
+
+    A value of '1' indicates that the driver should enable IP checksum
+    offload for received packets (both UDP and TCP) to the adapter hardware.
+
+RxFCHighThresh
+--------------
+:Valid Range: 1,536-262,136 (0x600 - 0x3FFF8, 8 byte granularity)
+:Default Value: 196,608 (0x30000)
+
+    Receive Flow control high threshold (when we send a pause frame)
+
+RxFCLowThresh
+-------------
+:Valid Range: 64-262,136 (0x40 - 0x3FFF8, 8 byte granularity)
+:Default Value: 163,840 (0x28000)
+
+    Receive Flow control low threshold (when we send a resume frame)
+
+FCReqTimeout
+------------
+:Valid Range: 1-65535
+:Default Value: 65535
+
+    Flow control request timeout (how long to pause the link partner's tx)
+
+IntDelayEnable
+--------------
+:Value Range: 0,1
+:Default Value: 1
+
+    Interrupt Delay, 0 disables transmit interrupt delay and 1 enables it.
+
+
+Improving Performance
+=====================
+
+With the 10 Gigabit server adapters, the default Linux configuration will
+very likely limit the total available throughput artificially.  There is a set
+of configuration changes that, when applied together, will increase the ability
+of Linux to transmit and receive data.  The following enhancements were
+originally acquired from settings published at http://www.spec.org/web99/ for
+various submitted results using Linux.
+
+NOTE:
+  These changes are only suggestions, and serve as a starting point for
+  tuning your network performance.
+
+The changes are made in three major ways, listed in order of greatest effect:
+
+- Use ip link to modify the mtu (maximum transmission unit) and the txqueuelen
+  parameter.
+- Use sysctl to modify /proc parameters (essentially kernel tuning)
+- Use setpci to modify the MMRBC field in PCI-X configuration space to increase
+  transmit burst lengths on the bus.
+
+NOTE:
+  setpci modifies the adapter's configuration registers to allow it to read
+  up to 4k bytes at a time (for transmits).  However, for some systems the
+  behavior after modifying this register may be undefined (possibly errors of
+  some kind).  A power-cycle, hard reset or explicitly setting the e6 register
+  back to 22 (setpci -d 8086:1a48 e6.b=22) may be required to get back to a
+  stable configuration.
+
+- COPY these lines and paste them into ixgb_perf.sh:
+
+::
+
+  #!/bin/bash
+  echo "configuring network performance , edit this file to change the interface
+  or device ID of 10GbE card"
+  # set mmrbc to 4k reads, modify only Intel 10GbE device IDs
+  # replace 1a48 with appropriate 10GbE device's ID installed on the system,
+  # if needed.
+  setpci -d 8086:1a48 e6.b=2e
+  # set the MTU (max transmission unit) - it requires your switch and clients
+  # to change as well.
+  # set the txqueuelen
+  # your ixgb adapter should be loaded as eth1 for this to work, change if needed
+  ip li set dev eth1 mtu 9000 txqueuelen 1000 up
+  # call the sysctl utility to modify /proc/sys entries
+  sysctl -p ./sysctl_ixgb.conf
+
+- COPY these lines and paste them into sysctl_ixgb.conf:
+
+::
+
+  # some of the defaults may be different for your kernel
+  # call this file with sysctl -p <this file>
+  # these are just suggested values that worked well to increase throughput in
+  # several network benchmark tests, your mileage may vary
+
+  ### IPV4 specific settings
+  # turn TCP timestamp support off, default 1, reduces CPU use
+  net.ipv4.tcp_timestamps = 0
+  # turn SACK support off, default on
+  # on systems with a VERY fast bus -> memory interface this is the big gainer
+  net.ipv4.tcp_sack = 0
+  # set min/default/max TCP read buffer, default 4096 87380 174760
+  net.ipv4.tcp_rmem = 10000000 10000000 10000000
+  # set min/pressure/max TCP write buffer, default 4096 16384 131072
+  net.ipv4.tcp_wmem = 10000000 10000000 10000000
+  # set min/pressure/max TCP buffer space, default 31744 32256 32768
+  net.ipv4.tcp_mem = 10000000 10000000 10000000
+
+  ### CORE settings (mostly for socket and UDP effect)
+  # set maximum receive socket buffer size, default 131071
+  net.core.rmem_max = 524287
+  # set maximum send socket buffer size, default 131071
+  net.core.wmem_max = 524287
+  # set default receive socket buffer size, default 65535
+  net.core.rmem_default = 524287
+  # set default send socket buffer size, default 65535
+  net.core.wmem_default = 524287
+  # set maximum amount of option memory buffers, default 10240
+  net.core.optmem_max = 524287
+  # set number of unprocessed input packets before kernel starts dropping them; default 300
+  net.core.netdev_max_backlog = 300000
+
+Edit the ixgb_perf.sh script if necessary to change eth1 to whatever interface
+your ixgb driver is using and/or replace '1a48' with appropriate 10GbE device's
+ID installed on the system.
+
+NOTE:
+  Unless these scripts are added to the boot process, these changes will
+  only last only until the next system reboot.
+
+
+Resolving Slow UDP Traffic
+--------------------------
+If your server does not seem to be able to receive UDP traffic as fast as it
+can receive TCP traffic, it could be because Linux, by default, does not set
+the network stack buffers as large as they need to be to support high UDP
+transfer rates.  One way to alleviate this problem is to allow more memory to
+be used by the IP stack to store incoming data.
+
+For instance, use the commands::
+
+    sysctl -w net.core.rmem_max=262143
+
+and::
+
+    sysctl -w net.core.rmem_default=262143
+
+to increase the read buffer memory max and default to 262143 (256k - 1) from
+defaults of max=131071 (128k - 1) and default=65535 (64k - 1).  These variables
+will increase the amount of memory used by the network stack for receives, and
+can be increased significantly more if necessary for your application.
+
+
+Additional Configurations
+=========================
+
+Configuring the Driver on Different Distributions
+-------------------------------------------------
+Configuring a network driver to load properly when the system is started is
+distribution dependent. Typically, the configuration process involves adding
+an alias line to /etc/modprobe.conf as well as editing other system startup
+scripts and/or configuration files.  Many popular Linux distributions ship
+with tools to make these changes for you.  To learn the proper way to
+configure a network device for your system, refer to your distribution
+documentation.  If during this process you are asked for the driver or module
+name, the name for the Linux Base Driver for the Intel 10GbE Family of
+Adapters is ixgb.
+
+Viewing Link Messages
+---------------------
+Link messages will not be displayed to the console if the distribution is
+restricting system messages. In order to see network driver link messages on
+your console, set dmesg to eight by entering the following::
+
+    dmesg -n 8
+
+NOTE: This setting is not saved across reboots.
+
+Jumbo Frames
+------------
+The driver supports Jumbo Frames for all adapters. Jumbo Frames support is
+enabled by changing the MTU to a value larger than the default of 1500.
+The maximum value for the MTU is 16114.  Use the ip command to
+increase the MTU size.  For example::
+
+    ip li set dev ethx mtu 9000
+
+The maximum MTU setting for Jumbo Frames is 16114.  This value coincides
+with the maximum Jumbo Frames size of 16128.
+
+Ethtool
+-------
+The driver utilizes the ethtool interface for driver configuration and
+diagnostics, as well as displaying statistical information.  The ethtool
+version 1.6 or later is required for this functionality.
+
+The latest release of ethtool can be found from
+https://www.kernel.org/pub/software/network/ethtool/
+
+NOTE:
+  The ethtool version 1.6 only supports a limited set of ethtool options.
+  Support for a more complete ethtool feature set can be enabled by
+  upgrading to the latest version.
+
+NAPI
+----
+NAPI (Rx polling mode) is supported in the ixgb driver.
+
+See https://wiki.linuxfoundation.org/networking/napi for more information on
+NAPI.
+
+
+Known Issues/Troubleshooting
+============================
+
+NOTE:
+  After installing the driver, if your Intel Network Connection is not
+  working, verify in the "In This Release" section of the readme that you have
+  installed the correct driver.
+
+Cable Interoperability Issue with Fujitsu XENPAK Module in SmartBits Chassis
+----------------------------------------------------------------------------
+Excessive CRC errors may be observed if the Intel(R) PRO/10GbE CX4
+Server adapter is connected to a Fujitsu XENPAK CX4 module in a SmartBits
+chassis using 15 m/24AWG cable assemblies manufactured by Fujitsu or Leoni.
+The CRC errors may be received either by the Intel(R) PRO/10GbE CX4
+Server adapter or the SmartBits. If this situation occurs using a different
+cable assembly may resolve the issue.
+
+Cable Interoperability Issues with HP Procurve 3400cl Switch Port
+-----------------------------------------------------------------
+Excessive CRC errors may be observed if the Intel(R) PRO/10GbE CX4 Server
+adapter is connected to an HP Procurve 3400cl switch port using short cables
+(1 m or shorter). If this situation occurs, using a longer cable may resolve
+the issue.
+
+Excessive CRC errors may be observed using Fujitsu 24AWG cable assemblies that
+Are 10 m or longer or where using a Leoni 15 m/24AWG cable assembly. The CRC
+errors may be received either by the CX4 Server adapter or at the switch. If
+this situation occurs, using a different cable assembly may resolve the issue.
+
+Jumbo Frames System Requirement
+-------------------------------
+Memory allocation failures have been observed on Linux systems with 64 MB
+of RAM or less that are running Jumbo Frames.  If you are using Jumbo
+Frames, your system may require more than the advertised minimum
+requirement of 64 MB of system memory.
+
+Performance Degradation with Jumbo Frames
+-----------------------------------------
+Degradation in throughput performance may be observed in some Jumbo frames
+environments.  If this is observed, increasing the application's socket buffer
+size and/or increasing the /proc/sys/net/ipv4/tcp_*mem entry values may help.
+See the specific application manual and /usr/src/linux*/Documentation/
+networking/ip-sysctl.txt for more details.
+
+Allocating Rx Buffers when Using Jumbo Frames
+---------------------------------------------
+Allocating Rx buffers when using Jumbo Frames on 2.6.x kernels may fail if
+the available memory is heavily fragmented. This issue may be seen with PCI-X
+adapters or with packet split disabled. This can be reduced or eliminated
+by changing the amount of available memory for receive buffer allocation, by
+increasing /proc/sys/vm/min_free_kbytes.
+
+Multiple Interfaces on Same Ethernet Broadcast Network
+------------------------------------------------------
+Due to the default ARP behavior on Linux, it is not possible to have
+one system on two IP networks in the same Ethernet broadcast domain
+(non-partitioned switch) behave as expected.  All Ethernet interfaces
+will respond to IP traffic for any IP address assigned to the system.
+This results in unbalanced receive traffic.
+
+If you have multiple interfaces in a server, do either of the following:
+
+  - Turn on ARP filtering by entering::
+
+      echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter
+
+  - Install the interfaces in separate broadcast domains - either in
+    different switches or in a switch partitioned to VLANs.
+
+UDP Stress Test Dropped Packet Issue
+--------------------------------------
+Under small packets UDP stress test with 10GbE driver, the Linux system
+may drop UDP packets due to the fullness of socket buffers. You may want
+to change the driver's Flow Control variables to the minimum value for
+controlling packet reception.
+
+Tx Hangs Possible Under Stress
+------------------------------
+Under stress conditions, if TX hangs occur, turning off TSO
+"ethtool -K eth0 tso off" may resolve the problem.

-Building and Installation
-=========================
-
-select m for "Intel(R) PRO/10GbE support" located at:
-      Location:
-        -> Device Drivers
-          -> Network device support (NETDEVICES [=y])
-            -> Ethernet (10000 Mbit) (NETDEV_10000 [=y])
-1. make modules && make modules_install
-
-2. Load the module:
-
-    modprobe ixgb <parameter>=<value>
-
-   The insmod command can be used if the full
-   path to the driver module is specified.  For example:
-
-     insmod /lib/modules/<KERNEL VERSION>/kernel/drivers/net/ixgb/ixgb.ko
-
-   With 2.6 based kernels also make sure that older ixgb drivers are
-   removed from the kernel, before loading the new module:
-
-     rmmod ixgb; modprobe ixgb
-
-3. Assign an IP address to the interface by entering the following, where
-   x is the interface number:
-
-     ip addr add ethx <IP_address>
-
-4. Verify that the interface works. Enter the following, where <IP_address>
-   is the IP address for another machine on the same subnet as the interface
-   that is being tested:
-
-     ping  <IP_address>
-
-
-Command Line Parameters
-=======================
-
-If the driver is built as a module, the  following optional parameters are
-used by entering them on the command line with the modprobe command using
-this syntax:
-
-     modprobe ixgb [<option>=<VAL1>,<VAL2>,...]
-
-For example, with two 10GbE PCI adapters, entering:
-
-     modprobe ixgb TxDescriptors=80,128
-
-loads the ixgb driver with 80 TX resources for the first adapter and 128 TX
-resources for the second adapter.
-
-The default value for each parameter is generally the recommended setting,
-unless otherwise noted.
-
-FlowControl
-Valid Range: 0-3 (0=none, 1=Rx only, 2=Tx only, 3=Rx&Tx)
-Default: Read from the EEPROM
-         If EEPROM is not detected, default is 1
-    This parameter controls the automatic generation(Tx) and response(Rx) to
-    Ethernet PAUSE frames.  There are hardware bugs associated with enabling
-    Tx flow control so beware.
-
-RxDescriptors
-Valid Range: 64-512
-Default Value: 512
-    This value is the number of receive descriptors allocated by the driver.
-    Increasing this value allows the driver to buffer more incoming packets.
-    Each descriptor is 16 bytes.  A receive buffer is also allocated for
-    each descriptor and can be either 2048, 4056, 8192, or 16384 bytes,
-    depending on the MTU setting.  When the MTU size is 1500 or less, the
-    receive buffer size is 2048 bytes. When the MTU is greater than 1500 the
-    receive buffer size will be either 4056, 8192, or 16384 bytes.  The
-    maximum MTU size is 16114.
-
-RxIntDelay
-Valid Range: 0-65535 (0=off)
-Default Value: 72
-    This value delays the generation of receive interrupts in units of
-    0.8192 microseconds.  Receive interrupt reduction can improve CPU
-    efficiency if properly tuned for specific network traffic.  Increasing
-    this value adds extra latency to frame reception and can end up
-    decreasing the throughput of TCP traffic.  If the system is reporting
-    dropped receives, this value may be set too high, causing the driver to
-    run out of available receive descriptors.
-
-TxDescriptors
-Valid Range: 64-4096
-Default Value: 256
-    This value is the number of transmit descriptors allocated by the driver.
-    Increasing this value allows the driver to queue more transmits.  Each
-    descriptor is 16 bytes.
-
-XsumRX
-Valid Range: 0-1
-Default Value: 1
-    A value of '1' indicates that the driver should enable IP checksum
-    offload for received packets (both UDP and TCP) to the adapter hardware.
-
-
-Improving Performance
-=====================
-
-With the 10 Gigabit server adapters, the default Linux configuration will
-very likely limit the total available throughput artificially.  There is a set
-of configuration changes that, when applied together, will increase the ability
-of Linux to transmit and receive data.  The following enhancements were
-originally acquired from settings published at http://www.spec.org/web99/ for
-various submitted results using Linux.
-
-NOTE: These changes are only suggestions, and serve as a starting point for
-      tuning your network performance.
-
-The changes are made in three major ways, listed in order of greatest effect:
-- Use ip link to modify the mtu (maximum transmission unit) and the txqueuelen
-  parameter.
-- Use sysctl to modify /proc parameters (essentially kernel tuning)
-- Use setpci to modify the MMRBC field in PCI-X configuration space to increase
-  transmit burst lengths on the bus.
-
-NOTE: setpci modifies the adapter's configuration registers to allow it to read
-up to 4k bytes at a time (for transmits).  However, for some systems the
-behavior after modifying this register may be undefined (possibly errors of
-some kind).  A power-cycle, hard reset or explicitly setting the e6 register
-back to 22 (setpci -d 8086:1a48 e6.b=22) may be required to get back to a
-stable configuration.
-
-- COPY these lines and paste them into ixgb_perf.sh:
-#!/bin/bash
-echo "configuring network performance , edit this file to change the interface
-or device ID of 10GbE card"
-# set mmrbc to 4k reads, modify only Intel 10GbE device IDs
-# replace 1a48 with appropriate 10GbE device's ID installed on the system,
-# if needed.
-setpci -d 8086:1a48 e6.b=2e
-# set the MTU (max transmission unit) - it requires your switch and clients
-# to change as well.
-# set the txqueuelen
-# your ixgb adapter should be loaded as eth1 for this to work, change if needed
-ip li set dev eth1 mtu 9000 txqueuelen 1000 up
-# call the sysctl utility to modify /proc/sys entries
-sysctl -p ./sysctl_ixgb.conf
-- END ixgb_perf.sh
-
-- COPY these lines and paste them into sysctl_ixgb.conf:
-# some of the defaults may be different for your kernel
-# call this file with sysctl -p <this file>
-# these are just suggested values that worked well to increase throughput in
-# several network benchmark tests, your mileage may vary
-
-### IPV4 specific settings
-# turn TCP timestamp support off, default 1, reduces CPU use
-net.ipv4.tcp_timestamps = 0
-# turn SACK support off, default on
-# on systems with a VERY fast bus -> memory interface this is the big gainer
-net.ipv4.tcp_sack = 0
-# set min/default/max TCP read buffer, default 4096 87380 174760
-net.ipv4.tcp_rmem = 10000000 10000000 10000000
-# set min/pressure/max TCP write buffer, default 4096 16384 131072
-net.ipv4.tcp_wmem = 10000000 10000000 10000000
-# set min/pressure/max TCP buffer space, default 31744 32256 32768
-net.ipv4.tcp_mem = 10000000 10000000 10000000
-
-### CORE settings (mostly for socket and UDP effect)
-# set maximum receive socket buffer size, default 131071
-net.core.rmem_max = 524287
-# set maximum send socket buffer size, default 131071
-net.core.wmem_max = 524287
-# set default receive socket buffer size, default 65535
-net.core.rmem_default = 524287
-# set default send socket buffer size, default 65535
-net.core.wmem_default = 524287
-# set maximum amount of option memory buffers, default 10240
-net.core.optmem_max = 524287
-# set number of unprocessed input packets before kernel starts dropping them; default 300
-net.core.netdev_max_backlog = 300000
-- END sysctl_ixgb.conf
-
-Edit the ixgb_perf.sh script if necessary to change eth1 to whatever interface
-your ixgb driver is using and/or replace '1a48' with appropriate 10GbE device's
-ID installed on the system.
-
-NOTE: Unless these scripts are added to the boot process, these changes will
-      only last only until the next system reboot.
-
-
-Resolving Slow UDP Traffic
---------------------------
-If your server does not seem to be able to receive UDP traffic as fast as it
-can receive TCP traffic, it could be because Linux, by default, does not set
-the network stack buffers as large as they need to be to support high UDP
-transfer rates.  One way to alleviate this problem is to allow more memory to
-be used by the IP stack to store incoming data.
-
-For instance, use the commands:
-    sysctl -w net.core.rmem_max=262143
-and
-    sysctl -w net.core.rmem_default=262143
-to increase the read buffer memory max and default to 262143 (256k - 1) from
-defaults of max=131071 (128k - 1) and default=65535 (64k - 1).  These variables
-will increase the amount of memory used by the network stack for receives, and
-can be increased significantly more if necessary for your application.
-
-
-Additional Configurations
-=========================
-
-  Configuring the Driver on Different Distributions
-  -------------------------------------------------
-  Configuring a network driver to load properly when the system is started is
-  distribution dependent. Typically, the configuration process involves adding
-  an alias line to /etc/modprobe.conf as well as editing other system startup
-  scripts and/or configuration files.  Many popular Linux distributions ship
-  with tools to make these changes for you.  To learn the proper way to
-  configure a network device for your system, refer to your distribution
-  documentation.  If during this process you are asked for the driver or module
-  name, the name for the Linux Base Driver for the Intel 10GbE Family of
-  Adapters is ixgb.
-
-  Viewing Link Messages
-  ---------------------
-  Link messages will not be displayed to the console if the distribution is
-  restricting system messages. In order to see network driver link messages on
-  your console, set dmesg to eight by entering the following:
-
-       dmesg -n 8
-
-  NOTE: This setting is not saved across reboots.
-
-
-  Jumbo Frames
-  ------------
-  The driver supports Jumbo Frames for all adapters. Jumbo Frames support is
-  enabled by changing the MTU to a value larger than the default of 1500.
-  The maximum value for the MTU is 16114.  Use the ip command to
-  increase the MTU size.  For example:
-
-        ip li set dev ethx mtu 9000
-
-  The maximum MTU setting for Jumbo Frames is 16114.  This value coincides
-  with the maximum Jumbo Frames size of 16128.
-
-
-  ethtool
-  -------
-  The driver utilizes the ethtool interface for driver configuration and
-  diagnostics, as well as displaying statistical information.  The ethtool
-  version 1.6 or later is required for this functionality.
-
-  The latest release of ethtool can be found from
-  https://www.kernel.org/pub/software/network/ethtool/
-
-  NOTE: The ethtool version 1.6 only supports a limited set of ethtool options.
-        Support for a more complete ethtool feature set can be enabled by
-        upgrading to the latest version.
-
-
-  NAPI
-  ----
-
-  NAPI (Rx polling mode) is supported in the ixgb driver.  NAPI is enabled
-  or disabled based on the configuration of the kernel.  see CONFIG_IXGB_NAPI
-
-  See www.cyberus.ca/~hadi/usenix-paper.tgz for more information on NAPI.
-
-
-Known Issues/Troubleshooting
-============================
-
-  NOTE: After installing the driver, if your Intel Network Connection is not
-  working, verify in the "In This Release" section of the readme that you have
-  installed the correct driver.
-
-  Intel(R) PRO/10GbE CX4 Server Adapter Cable Interoperability Issue with
-  Fujitsu XENPAK Module in SmartBits Chassis
-  ---------------------------------------------------------------------
-  Excessive CRC errors may be observed if the Intel(R) PRO/10GbE CX4
-  Server adapter is connected to a Fujitsu XENPAK CX4 module in a SmartBits
-  chassis using 15 m/24AWG cable assemblies manufactured by Fujitsu or Leoni.
-  The CRC errors may be received either by the Intel(R) PRO/10GbE CX4
-  Server adapter or the SmartBits. If this situation occurs using a different
-  cable assembly may resolve the issue.
-
-  CX4 Server Adapter Cable Interoperability Issues with HP Procurve 3400cl
-  Switch Port
-  ------------------------------------------------------------------------
-  Excessive CRC errors may be observed if the Intel(R) PRO/10GbE CX4 Server
-  adapter is connected to an HP Procurve 3400cl switch port using short cables
-  (1 m or shorter). If this situation occurs, using a longer cable may resolve
-  the issue.
-
-  Excessive CRC errors may be observed using Fujitsu 24AWG cable assemblies that
-  Are 10 m or longer or where using a Leoni 15 m/24AWG cable assembly. The CRC
-  errors may be received either by the CX4 Server adapter or at the switch. If
-  this situation occurs, using a different cable assembly may resolve the issue.
-
-
-  Jumbo Frames System Requirement
-  -------------------------------
-  Memory allocation failures have been observed on Linux systems with 64 MB
-  of RAM or less that are running Jumbo Frames.  If you are using Jumbo
-  Frames, your system may require more than the advertised minimum
-  requirement of 64 MB of system memory.
-
-
-  Performance Degradation with Jumbo Frames
-  -----------------------------------------
-  Degradation in throughput performance may be observed in some Jumbo frames
-  environments.  If this is observed, increasing the application's socket buffer
-  size and/or increasing the /proc/sys/net/ipv4/tcp_*mem entry values may help.
-  See the specific application manual and /usr/src/linux*/Documentation/
-  networking/ip-sysctl.txt for more details.
-
-
-  Allocating Rx Buffers when Using Jumbo Frames
-  ---------------------------------------------
-  Allocating Rx buffers when using Jumbo Frames on 2.6.x kernels may fail if
-  the available memory is heavily fragmented. This issue may be seen with PCI-X
-  adapters or with packet split disabled. This can be reduced or eliminated
-  by changing the amount of available memory for receive buffer allocation, by
-  increasing /proc/sys/vm/min_free_kbytes.
-
-
-  Multiple Interfaces on Same Ethernet Broadcast Network
-  ------------------------------------------------------
-  Due to the default ARP behavior on Linux, it is not possible to have
-  one system on two IP networks in the same Ethernet broadcast domain
-  (non-partitioned switch) behave as expected.  All Ethernet interfaces
-  will respond to IP traffic for any IP address assigned to the system.
-  This results in unbalanced receive traffic.
-
-  If you have multiple interfaces in a server, do either of the following:
-
-  - Turn on ARP filtering by entering:
-      echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter
-
-  - Install the interfaces in separate broadcast domains - either in
-    different switches or in a switch partitioned to VLANs.
-
-
-  UDP Stress Test Dropped Packet Issue
-  --------------------------------------
-  Under small packets UDP stress test with 10GbE driver, the Linux system
-  may drop UDP packets due to the fullness of socket buffers. You may want
-  to change the driver's Flow Control variables to the minimum value for
-  controlling packet reception.
-
-
-  Tx Hangs Possible Under Stress
-  ------------------------------
-  Under stress conditions, if TX hangs occur, turning off TSO
-  "ethtool -K eth0 tso off" may resolve the problem.

+
+Command Line Parameters
+=======================
+
+max_vfs
+-------
+:Valid Range: 1-63
+
+This parameter adds support for SR-IOV. It causes the driver to spawn up to
+max_vfs worth of virtual functions.
+If the value is greater than 0 it will also force the VMDq parameter to be 1 or
+more.
+
+NOTE: This parameter is only used on kernel 3.7.x and below. On kernel 3.8.x
+and above, use sysfs to enable VFs. Also, for Red Hat distributions, this
+parameter is only used on version 6.6 and older. For version 6.7 and newer, use
+sysfs. For example::
+
+  #echo $num_vf_enabled > /sys/class/net/$dev/device/sriov_numvfs // enable VFs
+  #echo 0 > /sys/class/net/$dev/device/sriov_numvfs               //disable VFs
+
+The parameters for the driver are referenced by position. Thus, if you have a
+dual port adapter, or more than one adapter in your system, and want N virtual
+functions per port, you must specify a number for each port with each parameter
+separated by a comma. For example::
+
+  modprobe ixgbe max_vfs=4
+
+This will spawn 4 VFs on the first port.
+
+::
+
+  modprobe ixgbe max_vfs=2,4
+
+This will spawn 2 VFs on the first port and 4 VFs on the second port.
+
+NOTE: Caution must be used in loading the driver with these parameters.
+Depending on your system configuration, number of slots, etc., it is impossible
+to predict in all cases where the positions would be on the command line.
+
+NOTE: Neither the device nor the driver control how VFs are mapped into config
+space. Bus layout will vary by operating system. On operating systems that
+support it, you can check sysfs to find the mapping.
+
+NOTE: When either SR-IOV mode or VMDq mode is enabled, hardware VLAN filtering
+and VLAN tag stripping/insertion will remain enabled. Please remove the old
+VLAN filter before the new VLAN filter is added. For example,
+
+::
+
+  ip link set eth0 vf 0 vlan 100 // set VLAN 100 for VF 0
+  ip link set eth0 vf 0 vlan 0   // Delete VLAN 100
+  ip link set eth0 vf 0 vlan 200 // set a new VLAN 200 for VF 0
+
+With kernel 3.6, the driver supports the simultaneous usage of max_vfs and DCB
+features, subject to the constraints described below. Prior to kernel 3.6, the
+driver did not support the simultaneous operation of max_vfs greater than 0 and
+the DCB features (multiple traffic classes utilizing Priority Flow Control and
+Extended Transmission Selection).
+
+When DCB is enabled, network traffic is transmitted and received through
+multiple traffic classes (packet buffers in the NIC). The traffic is associated
+with a specific class based on priority, which has a value of 0 through 7 used
+in the VLAN tag. When SR-IOV is not enabled, each traffic class is associated
+with a set of receive/transmit descriptor queue pairs. The number of queue
+pairs for a given traffic class depends on the hardware configuration. When
+SR-IOV is enabled, the descriptor queue pairs are grouped into pools. The
+Physical Function (PF) and each Virtual Function (VF) is allocated a pool of
+receive/transmit descriptor queue pairs. When multiple traffic classes are
+configured (for example, DCB is enabled), each pool contains a queue pair from
+each traffic class. When a single traffic class is configured in the hardware,
+the pools contain multiple queue pairs from the single traffic class.
+
+The number of VFs that can be allocated depends on the number of traffic
+classes that can be enabled. The configurable number of traffic classes for
+each enabled VF is as follows:
+0 - 15 VFs = Up to 8 traffic classes, depending on device support
+16 - 31 VFs = Up to 4 traffic classes
+32 - 63 VFs = 1 traffic class
+
+When VFs are configured, the PF is allocated one pool as well. The PF supports
+the DCB features with the constraint that each traffic class will only use a
+single queue pair. When zero VFs are configured, the PF can support multiple
+queue pairs per traffic class.
+
+allow_unsupported_sfp
+---------------------
+:Valid Range: 0,1
+:Default Value: 0 (disabled)
+
+This parameter allows unsupported and untested SFP+ modules on 82599-based
+adapters, as long as the type of module is known to the driver.
+
+debug
+-----
+:Valid Range: 0-16 (0=none,...,16=all)
+:Default Value: 0
+
+This parameter adjusts the level of debug messages displayed in the system
+logs.
+
+
+Additional Features and Configurations
+======================================
+
+Flow Control
+------------
+Ethernet Flow Control (IEEE 802.3x) can be configured with ethtool to enable
+receiving and transmitting pause frames for ixgbe. When transmit is enabled,
+pause frames are generated when the receive packet buffer crosses a predefined
+threshold. When receive is enabled, the transmit unit will halt for the time
+delay specified when a pause frame is received.
+
+NOTE: You must have a flow control capable link partner.
+
+Flow Control is enabled by default.
+
+Use ethtool to change the flow control settings. To enable or disable Rx or
+Tx Flow Control::
+
+  ethtool -A eth? rx <on|off> tx <on|off>
+
+Note: This command only enables or disables Flow Control if auto-negotiation is
+disabled. If auto-negotiation is enabled, this command changes the parameters
+used for auto-negotiation with the link partner.
+
+To enable or disable auto-negotiation::
+
+  ethtool -s eth? autoneg <on|off>
+
+Note: Flow Control auto-negotiation is part of link auto-negotiation. Depending
+on your device, you may not be able to change the auto-negotiation setting.
+
+NOTE: For 82598 backplane cards entering 1 gigabit mode, flow control default
+behavior is changed to off. Flow control in 1 gigabit mode on these devices can
+lead to transmit hangs.
+
+Intel(R) Ethernet Flow Director
+-------------------------------
+The Intel Ethernet Flow Director performs the following tasks:
+
+- Directs receive packets according to their flows to different queues.
+- Enables tight control on routing a flow in the platform.
+- Matches flows and CPU cores for flow affinity.
+- Supports multiple parameters for flexible flow classification and load
+  balancing (in SFP mode only).
+
+NOTE: Intel Ethernet Flow Director masking works in the opposite manner from
+subnet masking. In the following command::
+
+  #ethtool -N eth11 flow-type ip4 src-ip 172.4.1.2 m 255.0.0.0 dst-ip \
+  172.21.1.1 m 255.128.0.0 action 31
+
+The src-ip value that is written to the filter will be 0.4.1.2, not 172.0.0.0
+as might be expected. Similarly, the dst-ip value written to the filter will be
+0.21.1.1, not 172.0.0.0.
+
+To enable or disable the Intel Ethernet Flow Director::
+
+  # ethtool -K ethX ntuple <on|off>
+
+When disabling ntuple filters, all the user programmed filters are flushed from
+the driver cache and hardware. All needed filters must be re-added when ntuple
+is re-enabled.
+
+To add a filter that directs packet to queue 2, use -U or -N switch::
+
+  # ethtool -N ethX flow-type tcp4 src-ip 192.168.10.1 dst-ip \
+  192.168.10.2 src-port 2000 dst-port 2001 action 2 [loc 1]
+
+To see the list of filters currently present::
+
+  # ethtool <-u|-n> ethX
+
+Sideband Perfect Filters
+------------------------
+Sideband Perfect Filters are used to direct traffic that matches specified
+characteristics. They are enabled through ethtool's ntuple interface. To add a
+new filter use the following command::
+
+  ethtool -U <device> flow-type <type> src-ip <ip> dst-ip <ip> src-port <port> \
+  dst-port <port> action <queue>
+
+Where:
+  <device> - the ethernet device to program
+  <type> - can be ip4, tcp4, udp4, or sctp4
+  <ip> - the IP address to match on
+  <port> - the port number to match on
+  <queue> - the queue to direct traffic towards (-1 discards the matched traffic)
+
+Use the following command to delete a filter::
+
+  ethtool -U <device> delete <N>
+
+Where <N> is the filter id displayed when printing all the active filters, and
+may also have been specified using "loc <N>" when adding the filter.
+
+The following example matches TCP traffic sent from 192.168.0.1, port 5300,
+directed to 192.168.0.5, port 80, and sends it to queue 7::
+
+  ethtool -U enp130s0 flow-type tcp4 src-ip 192.168.0.1 dst-ip 192.168.0.5 \
+  src-port 5300 dst-port 80 action 7
+
+For each flow-type, the programmed filters must all have the same matching
+input set. For example, issuing the following two commands is acceptable::
+
+  ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.1 src-port 5300 action 7
+  ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.5 src-port 55 action 10
+
+Issuing the next two commands, however, is not acceptable, since the first
+specifies src-ip and the second specifies dst-ip::
+
+  ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.1 src-port 5300 action 7
+  ethtool -U enp130s0 flow-type ip4 dst-ip 192.168.0.5 src-port 55 action 10
+
+The second command will fail with an error. You may program multiple filters
+with the same fields, using different values, but, on one device, you may not
+program two TCP4 filters with different matching fields.
+
+Matching on a sub-portion of a field is not supported by the ixgbe driver, thus
+partial mask fields are not supported.
+
+To create filters that direct traffic to a specific Virtual Function, use the
+"user-def" parameter. Specify the user-def as a 64 bit value, where the lower 32
+bits represents the queue number, while the next 8 bits represent which VF.
+Note that 0 is the PF, so the VF identifier is offset by 1. For example::
+
+  ... user-def 0x800000002 ...
+
+specifies to direct traffic to Virtual Function 7 (8 minus 1) into queue 2 of
+that VF.
+
+Note that these filters will not break internal routing rules, and will not
+route traffic that otherwise would not have been sent to the specified Virtual
+Function.
+
+Jumbo Frames
+------------
+Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)
+to a value larger than the default value of 1500.
+
+Use the ifconfig command to increase the MTU size. For example, enter the
+following where <x> is the interface number::
+
+  ifconfig eth<x> mtu 9000 up
+
+Alternatively, you can use the ip command as follows::
+
+  ip link set mtu 9000 dev eth<x>
+  ip link set up dev eth<x>
+
+This setting is not saved across reboots. The setting change can be made
+permanent by adding 'MTU=9000' to the file::
+
+  /etc/sysconfig/network-scripts/ifcfg-eth<x> // for RHEL
+  /etc/sysconfig/network/<config_file> // for SLES
+
+NOTE: The maximum MTU setting for Jumbo Frames is 9710. This value coincides
+with the maximum Jumbo Frames size of 9728 bytes.
+
+NOTE: This driver will attempt to use multiple page sized buffers to receive
+each jumbo packet. This should help to avoid buffer starvation issues when
+allocating receive packets.
+
+NOTE: For 82599-based network connections, if you are enabling jumbo frames in
+a virtual function (VF), jumbo frames must first be enabled in the physical
+function (PF). The VF MTU setting cannot be larger than the PF MTU.
+
+Generic Receive Offload, aka GRO
+--------------------------------
+The driver supports the in-kernel software implementation of GRO. GRO has
+shown that by coalescing Rx traffic into larger chunks of data, CPU
+utilization can be significantly reduced when under large Rx load. GRO is an
+evolution of the previously-used LRO interface. GRO is able to coalesce
+other protocols besides TCP. It's also safe to use with configurations that
+are problematic for LRO, namely bridging and iSCSI.
+
+Data Center Bridging (DCB)
+--------------------------
+NOTE:
+The kernel assumes that TC0 is available, and will disable Priority Flow
+Control (PFC) on the device if TC0 is not available. To fix this, ensure TC0 is
+enabled when setting up DCB on your switch.
+
+DCB is a configuration Quality of Service implementation in hardware. It uses
+the VLAN priority tag (802.1p) to filter traffic. That means that there are 8
+different priorities that traffic can be filtered into. It also enables
+priority flow control (802.1Qbb) which can limit or eliminate the number of
+dropped packets during network stress. Bandwidth can be allocated to each of
+these priorities, which is enforced at the hardware level (802.1Qaz).
+
+Adapter firmware implements LLDP and DCBX protocol agents as per 802.1AB and
+802.1Qaz respectively. The firmware based DCBX agent runs in willing mode only
+and can accept settings from a DCBX capable peer. Software configuration of
+DCBX parameters via dcbtool/lldptool are not supported.
+
+The ixgbe driver implements the DCB netlink interface layer to allow user-space
+to communicate with the driver and query DCB configuration for the port.
+
+ethtool
+-------
+The driver utilizes the ethtool interface for driver configuration and
+diagnostics, as well as displaying statistical information. The latest ethtool
+version is required for this functionality. Download it at:
+https://www.kernel.org/pub/software/network/ethtool/
+
+FCoE
+----
+The ixgbe driver supports Fiber Channel over Ethernet (FCoE) and Data Center
+Bridging (DCB). This code has no default effect on the regular driver
+operation. Configuring DCB and FCoE is outside the scope of this README. Refer
+to http://www.open-fcoe.org/ for FCoE project information and contact
+ixgbe-eedc@lists.sourceforge.net for DCB information.
+
+MAC and VLAN anti-spoofing feature
+----------------------------------
+When a malicious driver attempts to send a spoofed packet, it is dropped by the
+hardware and not transmitted.
+
+An interrupt is sent to the PF driver notifying it of the spoof attempt. When a
+spoofed packet is detected, the PF driver will send the following message to
+the system log (displayed by the "dmesg" command)::
+
+  ixgbe ethX: ixgbe_spoof_check: n spoofed packets detected
+
+where "x" is the PF interface number; and "n" is number of spoofed packets.
+NOTE: This feature can be disabled for a specific Virtual Function (VF)::
+
+  ip link set <pf dev> vf <vf id> spoofchk {off|on}
+

-
-
-Flow Control
-------------
-Ethernet Flow Control (IEEE 802.3x) can be configured with ethtool to enable
-receiving and transmitting pause frames for ixgbe. When TX is enabled, PAUSE
-frames are generated when the receive packet buffer crosses a predefined
-threshold.  When rx is enabled, the transmit unit will halt for the time delay
-specified when a PAUSE frame is received.
-
-Flow Control is enabled by default. If you want to disable a flow control
-capable link partner, use ethtool:
-
-     ethtool -A eth? autoneg off RX off TX off
-
-NOTE: For 82598 backplane cards entering 1 gig mode, flow control default
-behavior is changed to off.  Flow control in 1 gig mode on these devices can
-lead to Tx hangs.
-
-Intel(R) Ethernet Flow Director
--------------------------------
-Supports advanced filters that direct receive packets by their flows to
-different queues. Enables tight control on routing a flow in the platform.
-Matches flows and CPU cores for flow affinity. Supports multiple parameters
-for flexible flow classification and load balancing.
-
-Flow director is enabled only if the kernel is multiple TX queue capable.
-
-An included script (set_irq_affinity.sh) automates setting the IRQ to CPU
-affinity.
-
-You can verify that the driver is using Flow Director by looking at the counter
-in ethtool: fdir_miss and fdir_match.
-
-Other ethtool Commands:
-To enable Flow Director
-	ethtool -K ethX ntuple on
-To add a filter
-	Use -U switch. e.g., ethtool -U ethX flow-type tcp4 src-ip 10.0.128.23
-        action 1
-To see the list of filters currently present:
-	ethtool -u ethX
-
-Perfect Filter: Perfect filter is an interface to load the filter table that
-funnels all flow into queue_0 unless an alternative queue is specified using
-"action". In that case, any flow that matches the filter criteria will be
-directed to the appropriate queue.
-
-If the queue is defined as -1, filter will drop matching packets.
-
-To account for filter matches and misses, there are two stats in ethtool:
-fdir_match and fdir_miss. In addition, rx_queue_N_packets shows the number of
-packets processed by the Nth queue.
-
-NOTE: Receive Packet Steering (RPS) and Receive Flow Steering (RFS) are not
-compatible with Flow Director. IF Flow Director is enabled, these will be
-disabled.
-
-The following three parameters impact Flow Director.
-
-FdirMode
---------
-Valid Range: 0-2 (0=off, 1=ATR, 2=Perfect filter mode)
-Default Value: 1
-
-  Flow Director filtering modes.
-
-FdirPballoc
------------
-Valid Range: 0-2 (0=64k, 1=128k, 2=256k)
-Default Value: 0
-
-  Flow Director allocated packet buffer size.
-
-AtrSampleRate
---------------
-Valid Range: 1-100
-Default Value: 20
-
-  Software ATR Tx packet sample rate. For example, when set to 20, every 20th
-  packet, looks to see if the packet will create a new flow.
-
-Node
-----
-Valid Range:   0-n
-Default Value: 1 (off)
-
-  0 - n: where n is the number of NUMA nodes (i.e. 0 - 3) currently online in
-  your system
-  1: turns this option off
-
-  The Node parameter will allow you to pick which NUMA node you want to have
-  the adapter allocate memory on.
-
-max_vfs
--------
-Valid Range:   1-63
-Default Value: 0
-
-  If the value is greater than 0 it will also force the VMDq parameter to be 1
-  or more.
-
-  This parameter adds support for SR-IOV.  It causes the driver to spawn up to
-  max_vfs worth of virtual function.
-
-
-Additional Configurations
-=========================
-
-  Jumbo Frames
-  ------------
-  The driver supports Jumbo Frames for all adapters. Jumbo Frames support is
-  enabled by changing the MTU to a value larger than the default of 1500.
-  The maximum value for the MTU is 16110.  Use the ip command to
-  increase the MTU size.  For example:
-
-        ip link set dev ethx mtu 9000
-
-  The maximum MTU setting for Jumbo Frames is 9710.  This value coincides
-  with the maximum Jumbo Frames size of 9728.
-
-  Generic Receive Offload, aka GRO
-  --------------------------------
-  The driver supports the in-kernel software implementation of GRO.  GRO has
-  shown that by coalescing Rx traffic into larger chunks of data, CPU
-  utilization can be significantly reduced when under large Rx load.  GRO is an
-  evolution of the previously-used LRO interface.  GRO is able to coalesce
-  other protocols besides TCP.  It's also safe to use with configurations that
-  are problematic for LRO, namely bridging and iSCSI.
-
-  Data Center Bridging, aka DCB
-  -----------------------------
-  DCB is a configuration Quality of Service implementation in hardware.
-  It uses the VLAN priority tag (802.1p) to filter traffic.  That means
-  that there are 8 different priorities that traffic can be filtered into.
-  It also enables priority flow control which can limit or eliminate the
-  number of dropped packets during network stress.  Bandwidth can be
-  allocated to each of these priorities, which is enforced at the hardware
-  level.
-
-  To enable DCB support in ixgbe, you must enable the DCB netlink layer to
-  allow the userspace tools (see below) to communicate with the driver.
-  This can be found in the kernel configuration here:
-
-        -> Networking support
-          -> Networking options
-            -> Data Center Bridging support
-
-  Once this is selected, DCB support must be selected for ixgbe.  This can
-  be found here:
-
-        -> Device Drivers
-          -> Network device support (NETDEVICES [=y])
-            -> Ethernet (10000 Mbit) (NETDEV_10000 [=y])
-              -> Intel(R) 10GbE PCI Express adapters support
-                -> Data Center Bridging (DCB) Support
-
-  After these options are selected, you must rebuild your kernel and your
-  modules.
-
-  In order to use DCB, userspace tools must be downloaded and installed.
-  The dcbd tools can be found at:
-
-        http://e1000.sf.net
-
-  Ethtool
-  -------
-  The driver utilizes the ethtool interface for driver configuration and
-  diagnostics, as well as displaying statistical information. The latest
-  ethtool version is required for this functionality.
-
-  The latest release of ethtool can be found from
-  https://www.kernel.org/pub/software/network/ethtool/
-
-  FCoE
-  ----
-  This release of the ixgbe driver contains new code to enable users to use
-  Fiber Channel over Ethernet (FCoE) and Data Center Bridging (DCB)
-  functionality that is supported by the 82598-based hardware.  This code has
-  no default effect on the regular driver operation, and configuring DCB and
-  FCoE is outside the scope of this driver README. Refer to
-  http://www.open-fcoe.org/ for FCoE project information and contact
-  e1000-eedc@lists.sourceforge.net for DCB information.
-
-  MAC and VLAN anti-spoofing feature
-  ----------------------------------
-  When a malicious driver attempts to send a spoofed packet, it is dropped by
-  the hardware and not transmitted.  An interrupt is sent to the PF driver
-  notifying it of the spoof attempt.
-
-  When a spoofed packet is detected the PF driver will send the following
-  message to the system log (displayed by  the "dmesg" command):
-
-  Spoof event(s) detected on VF (n)
-
-  Where n=the VF that attempted to do the spoofing.

-Known Issues
-============
-
-  Enabling SR-IOV in a 32-bit or 64-bit Microsoft* Windows* Server 2008/R2
-  Guest OS using Intel (R) 82576-based GbE or Intel (R) 82599-based 10GbE
-  controller under KVM
-  ------------------------------------------------------------------------
-  KVM Hypervisor/VMM supports direct assignment of a PCIe device to a VM.  This
-  includes traditional PCIe devices, as well as SR-IOV-capable devices using
-  Intel 82576-based and 82599-based controllers.
-
-  While direct assignment of a PCIe device or an SR-IOV Virtual Function (VF)
-  to a Linux-based VM running 2.6.32 or later kernel works fine, there is a
-  known issue with Microsoft Windows Server 2008 VM that results in a "yellow
-  bang" error. This problem is within the KVM VMM itself, not the Intel driver,
-  or the SR-IOV logic of the VMM, but rather that KVM emulates an older CPU
-  model for the guests, and this older CPU model does not support MSI-X
-  interrupts, which is a requirement for Intel SR-IOV.
-
-  If you wish to use the Intel 82576 or 82599-based controllers in SR-IOV mode
-  with KVM and a Microsoft Windows Server 2008 guest try the following
-  workaround. The workaround is to tell KVM to emulate a different model of CPU
-  when using qemu to create the KVM guest:
-
-       "-cpu qemu64,model=13"

-- Congestion control
-- How the new TCP output machine [nyi] works
-
-Congestion control
-==================
-
-The following variables are used in the tcp_sock for congestion control:
-snd_cwnd		The size of the congestion window
-snd_ssthresh		Slow start threshold. We are in slow start if
-			snd_cwnd is less than this.
-snd_cwnd_cnt		A counter used to slow down the rate of increase
-			once we exceed slow start threshold.
-snd_cwnd_clamp		This is the maximum size that snd_cwnd can grow to.
-snd_cwnd_stamp		Timestamp for when congestion window last validated.
-snd_cwnd_used		Used as a highwater mark for how much of the
-			congestion window is in use. It is used to adjust
-			snd_cwnd down when the link is limited by the
-			application rather than the network.
-
-As of 2.6.13, Linux supports pluggable congestion control algorithms.
-A congestion control mechanism can be registered through functions in
-tcp_cong.c. The functions used by the congestion control mechanism are
-registered via passing a tcp_congestion_ops struct to
-tcp_register_congestion_control. As a minimum, the congestion control
-mechanism must provide a valid name and must implement either ssthresh,
-cong_avoid and undo_cwnd hooks or the "omnipotent" cong_control hook.
-
-Private data for a congestion control mechanism is stored in tp->ca_priv.
-tcp_ca(tp) returns a pointer to this space.  This is preallocated space - it
-is important to check the size of your private data will fit this space, or
-alternatively, space could be allocated elsewhere and a pointer to it could
-be stored here.
-
-There are three kinds of congestion control algorithms currently: The
-simplest ones are derived from TCP reno (highspeed, scalable) and just
-provide an alternative congestion window calculation. More complex
-ones like BIC try to look at other events to provide better
-heuristics.  There are also round trip time based algorithms like
-Vegas and Westwood+.
-
-Good TCP congestion control is a complex problem because the algorithm
-needs to maintain fairness and performance. Please review current
-research and RFC's before developing new modules.
-
-The default congestion control mechanism is chosen based on the
-DEFAULT_TCP_CONG Kconfig parameter. If you really want a particular default
-value then you can set it using sysctl net.ipv4.tcp_congestion_control. The
-module will be autoloaded if needed and you will get the expected protocol. If
-you ask for an unknown congestion method, then the sysctl attempt will fail.
-
-If you remove a TCP congestion control module, then you will get the next
-available one. Since reno cannot be built as a module, and cannot be
-removed, it will always be available.
-
-How the new TCP output machine [nyi] works.
-===========================================
-
-Data is kept on a single queue. The skb->users flag tells us if the frame is
-one that has been queued already. To add a frame we throw it on the end. Ack
-walks down the list from the start.
-
-We keep a set of control flags
-
-
-	sk->tcp_pend_event
-
-		TCP_PEND_ACK			Ack needed
-		TCP_ACK_NOW			Needed now
-		TCP_WINDOW			Window update check
-		TCP_WINZERO			Zero probing
-
-
-	sk->transmit_queue		The transmission frame begin
-	sk->transmit_new		First new frame pointer
-	sk->transmit_end		Where to add frames
-
-	sk->tcp_last_tx_ack		Last ack seen
-	sk->tcp_dup_ack			Dup ack count for fast retransmit
-
-
-Frames are queued for output by tcp_write. We do our best to send the frames
-off immediately if possible, but otherwise queue and compute the body
-checksum in the copy. 
-
-When a write is done we try to clear any pending events and piggy back them.
-If the window is full we queue full sized frames. On the first timeout in
-zero window we split this.
-
-On a timer we walk the retransmit list to send any retransmits, update the
-backoff timers etc. A change of route table stamp causes a change of header
-and recompute. We add any new tcp level headers and refinish the checksum
-before sending.

+
+Linux Kernel Contributor Covenant Code of Conduct Interpretation
+================================================================
+
+The :ref:`code_of_conduct` is a general document meant to
+provide a set of rules for almost any open source community.  Every
+open-source community is unique and the Linux kernel is no exception.
+Because of this, this document describes how we in the Linux kernel
+community will interpret it.  We also do not expect this interpretation
+to be static over time, and will adjust it as needed.
+
+The Linux kernel development effort is a very personal process compared
+to "traditional" ways of developing software.  Your contributions and
+ideas behind them will be carefully reviewed, often resulting in
+critique and criticism.  The review will almost always require
+improvements before the material can be included in the
+kernel.  Know that this happens because everyone involved wants to see
+the best possible solution for the overall success of Linux.  This
+development process has been proven to create the most robust operating
+system kernel ever, and we do not want to do anything to cause the
+quality of submission and eventual result to ever decrease.
+
+Maintainers
+-----------
+
+The Code of Conduct uses the term "maintainers" numerous times.  In the
+kernel community, a "maintainer" is anyone who is responsible for a
+subsystem, driver, or file, and is listed in the MAINTAINERS file in the
+kernel source tree.
+
+Responsibilities
+----------------
+
+The Code of Conduct mentions rights and responsibilities for
+maintainers, and this needs some further clarifications.
+
+First and foremost, it is a reasonable expectation to have maintainers
+lead by example.
+
+That being said, our community is vast and broad, and there is no new
+requirement for maintainers to unilaterally handle how other people
+behave in the parts of the community where they are active.  That
+responsibility is upon all of us, and ultimately the Code of Conduct
+documents final escalation paths in case of unresolved concerns
+regarding conduct issues.
+
+Maintainers should be willing to help when problems occur, and work with
+others in the community when needed.  Do not be afraid to reach out to
+the Technical Advisory Board (TAB) or other maintainers if you're
+uncertain how to handle situations that come up.  It will not be
+considered a violation report unless you want it to be.  If you are
+uncertain about approaching the TAB or any other maintainers, please
+reach out to our conflict mediator, Mishi Choudhary <mishi@linux.com>.
+
+In the end, "be kind to each other" is really what the end goal is for
+everybody.  We know everyone is human and we all fail at times, but the
+primary goal for all of us should be to work toward amicable resolutions
+of problems.  Enforcement of the code of conduct will only be a last
+resort option.
+
+Our goal of creating a robust and technically advanced operating system
+and the technical complexity involved naturally require expertise and
+decision-making.
+
+The required expertise varies depending on the area of contribution.  It
+is determined mainly by context and technical complexity and only
+secondary by the expectations of contributors and maintainers.
+
+Both the expertise expectations and decision-making are subject to
+discussion, but at the very end there is a basic necessity to be able to
+make decisions in order to make progress.  This prerogative is in the
+hands of maintainers and project's leadership and is expected to be used
+in good faith.
+
+As a consequence, setting expertise expectations, making decisions and
+rejecting unsuitable contributions are not viewed as a violation of the
+Code of Conduct.
+
+While maintainers are in general welcoming to newcomers, their capacity
+of helping contributors overcome the entry hurdles is limited, so they
+have to set priorities.  This, also, is not to be seen as a violation of
+the Code of Conduct.  The kernel community is aware of that and provides
+entry level programs in various forms like kernelnewbies.org.
+
+Scope
+-----
+
+The Linux kernel community primarily interacts on a set of public email
+lists distributed around a number of different servers controlled by a
+number of different companies or individuals.  All of these lists are
+defined in the MAINTAINERS file in the kernel source tree.  Any emails
+sent to those mailing lists are considered covered by the Code of
+Conduct.
+
+Developers who use the kernel.org bugzilla, and other subsystem bugzilla
+or bug tracking tools should follow the guidelines of the Code of
+Conduct.  The Linux kernel community does not have an "official" project
+email address, or "official" social media address.  Any activity
+performed using a kernel.org email account must follow the Code of
+Conduct as published for kernel.org, just as any individual using a
+corporate email account must follow the specific rules of that
+corporation.
+
+The Code of Conduct does not prohibit continuing to include names, email
+addresses, and associated comments in mailing list messages, kernel
+change log messages, or code comments.
+
+Interaction in other forums is covered by whatever rules apply to said
+forums and is in general not covered by the Code of Conduct.  Exceptions
+may be considered for extreme circumstances.
+
+Contributions submitted for the kernel should use appropriate language.
+Content that already exists predating the Code of Conduct will not be
+addressed now as a violation.  Inappropriate language can be seen as a
+bug, though; such bugs will be fixed more quickly if any interested
+parties submit patches to that effect.  Expressions that are currently
+part of the user/kernel API, or reflect terminology used in published
+standards or specifications, are not considered bugs.
+
+Enforcement
+-----------
+
+The address listed in the Code of Conduct goes to the Code of Conduct
+Committee.  The exact members receiving these emails at any given time
+are listed at https://kernel.org/code-of-conduct.html.  Members can not
+access reports made before they joined or after they have left the
+committee.
+
+The initial Code of Conduct Committee consists of volunteer members of
+the TAB, as well as a professional mediator acting as a neutral third
+party.  The first task of the committee is to establish documented
+processes, which will be made public.
+
+Any member of the committee, including the mediator, can be contacted
+directly if a reporter does not wish to include the full committee in a
+complaint or concern.
+
+The Code of Conduct Committee reviews the cases according to the
+processes (see above) and consults with the TAB as needed and
+appropriate, for instance to request and receive information about the
+kernel community.
+
+Any decisions by the committee will be brought to the TAB, for
+implementation of enforcement with the relevant maintainers if needed.
+A decision by the Code of Conduct Committee can be overturned by the TAB
+by a two-thirds vote.
+
+At quarterly intervals, the Code of Conduct Committee and TAB will
+provide a report summarizing the anonymised reports that the Code of
+Conduct committee has received and their status, as well details of any
+overridden decisions including complete and identifiable voting details.
+
+We expect to establish a different process for Code of Conduct Committee
+staffing beyond the bootstrap period.  This document will be updated
+with that information when this occurs.

+=====================================================================
+Deprecated Interfaces, Language Features, Attributes, and Conventions
+=====================================================================
+
+In a perfect world, it would be possible to convert all instances of
+some deprecated API into the new API and entirely remove the old API in
+a single development cycle. However, due to the size of the kernel, the
+maintainership hierarchy, and timing, it's not always feasible to do these
+kinds of conversions at once. This means that new instances may sneak into
+the kernel while old ones are being removed, only making the amount of
+work to remove the API grow. In order to educate developers about what
+has been deprecated and why, this list has been created as a place to
+point when uses of deprecated things are proposed for inclusion in the
+kernel.
+
+__deprecated
+------------
+While this attribute does visually mark an interface as deprecated,
+it `does not produce warnings during builds any more
+<https://git.kernel.org/linus/771c035372a036f83353eef46dbb829780330234>`_
+because one of the standing goals of the kernel is to build without
+warnings and no one was actually doing anything to remove these deprecated
+interfaces. While using `__deprecated` is nice to note an old API in
+a header file, it isn't the full solution. Such interfaces must either
+be fully removed from the kernel, or added to this file to discourage
+others from using them in the future.
+
+open-coded arithmetic in allocator arguments
+--------------------------------------------
+Dynamic size calculations (especially multiplication) should not be
+performed in memory allocator (or similar) function arguments due to the
+risk of them overflowing. This could lead to values wrapping around and a
+smaller allocation being made than the caller was expecting. Using those
+allocations could lead to linear overflows of heap memory and other
+misbehaviors. (One exception to this is literal values where the compiler
+can warn if they might overflow. Though using literals for arguments as
+suggested below is also harmless.)
+
+For example, do not use ``count * size`` as an argument, as in::
+
+	foo = kmalloc(count * size, GFP_KERNEL);
+
+Instead, the 2-factor form of the allocator should be used::
+
+	foo = kmalloc_array(count, size, GFP_KERNEL);
+
+If no 2-factor form is available, the saturate-on-overflow helpers should
+be used::
+
+	bar = vmalloc(array_size(count, size));
+
+Another common case to avoid is calculating the size of a structure with
+a trailing array of others structures, as in::
+
+	header = kzalloc(sizeof(*header) + count * sizeof(*header->item),
+			 GFP_KERNEL);
+
+Instead, use the helper::
+
+	header = kzalloc(struct_size(header, item, count), GFP_KERNEL);
+
+See :c:func:`array_size`, :c:func:`array3_size`, and :c:func:`struct_size`,
+for more details as well as the related :c:func:`check_add_overflow` and
+:c:func:`check_mul_overflow` family of functions.
+
+simple_strtol(), simple_strtoll(), simple_strtoul(), simple_strtoull()
+----------------------------------------------------------------------
+The :c:func:`simple_strtol`, :c:func:`simple_strtoll`,
+:c:func:`simple_strtoul`, and :c:func:`simple_strtoull` functions
+explicitly ignore overflows, which may lead to unexpected results
+in callers. The respective :c:func:`kstrtol`, :c:func:`kstrtoll`,
+:c:func:`kstrtoul`, and :c:func:`kstrtoull` functions tend to be the
+correct replacements, though note that those require the string to be
+NUL or newline terminated.
+
+strcpy()
+--------
+:c:func:`strcpy` performs no bounds checking on the destination
+buffer. This could result in linear overflows beyond the
+end of the buffer, leading to all kinds of misbehaviors. While
+`CONFIG_FORTIFY_SOURCE=y` and various compiler flags help reduce the
+risk of using this function, there is no good reason to add new uses of
+this function. The safe replacement is :c:func:`strscpy`.
+
+strncpy() on NUL-terminated strings
+-----------------------------------
+Use of :c:func:`strncpy` does not guarantee that the destination buffer
+will be NUL terminated. This can lead to various linear read overflows
+and other misbehavior due to the missing termination. It also NUL-pads the
+destination buffer if the source contents are shorter than the destination
+buffer size, which may be a needless performance penalty for callers using
+only NUL-terminated strings. The safe replacement is :c:func:`strscpy`.
+(Users of :c:func:`strscpy` still needing NUL-padding will need an
+explicit :c:func:`memset` added.)
+
+If a caller is using non-NUL-terminated strings, :c:func:`strncpy()` can
+still be used, but destinations should be marked with the `__nonstring
+<https://gcc.gnu.org/onlinedocs/gcc/Common-Variable-Attributes.html>`_
+attribute to avoid future compiler warnings.
+
+strlcpy()
+---------
+:c:func:`strlcpy` reads the entire source buffer first, possibly exceeding
+the given limit of bytes to copy. This is inefficient and can lead to
+linear read overflows if a source string is not NUL-terminated. The
+safe replacement is :c:func:`strscpy`.
+
+Variable Length Arrays (VLAs)
+-----------------------------
+Using stack VLAs produces much worse machine code than statically
+sized stack arrays. While these non-trivial `performance issues
+<https://git.kernel.org/linus/02361bc77888>`_ are reason enough to
+eliminate VLAs, they are also a security risk. Dynamic growth of a stack
+array may exceed the remaining memory in the stack segment. This could
+lead to a crash, possible overwriting sensitive contents at the end of the
+stack (when built without `CONFIG_THREAD_INFO_IN_TASK=y`), or overwriting
+memory adjacent to the stack (when built without `CONFIG_VMAP_STACK=y`)

-completions - wait for completion handling
-==========================================
-
-This document was originally written based on 3.18.0 (linux-next)
+Completions - "wait for completion" barrier APIs
+================================================
 
 Introduction:
 -------------
 
-If you have one or more threads of execution that must wait for some process
+If you have one or more threads that must wait for some kernel activity
 to have reached a point or a specific state, completions can provide a
 race-free solution to this problem. Semantically they are somewhat like a
-pthread_barrier and have similar use-cases.
+pthread_barrier() and have similar use-cases.
 
 Completions are a code synchronization mechanism which is preferable to any
-misuse of locks. Any time you think of using yield() or some quirky
-msleep(1) loop to allow something else to proceed, you probably want to
-look into using one of the wait_for_completion*() calls instead. The
-advantage of using completions is clear intent of the code, but also more
-efficient code as both threads can continue until the result is actually
-needed.
-
-Completions are built on top of the generic event infrastructure in Linux,
-with the event reduced to a simple flag (appropriately called "done") in
-struct completion that tells the waiting threads of execution if they
-can continue safely.
-
-As completions are scheduling related, the code is found in
+misuse of locks/semaphores and busy-loops. Any time you think of using
+yield() or some quirky msleep(1) loop to allow something else to proceed,
+you probably want to look into using one of the wait_for_completion*()
+calls and complete() instead.
+
+The advantage of using completions is that they have a well defined, focused
+purpose which makes it very easy to see the intent of the code, but they
+also result in more efficient code as all threads can continue execution
+until the result is actually needed, and both the waiting and the signalling
+is highly efficient using low level scheduler sleep/wakeup facilities.
+
+Completions are built on top of the waitqueue and wakeup infrastructure of
+the Linux scheduler. The event the threads on the waitqueue are waiting for
+is reduced to a simple flag in 'struct completion', appropriately called "done".
+
+As completions are scheduling related, the code can be found in
 kernel/sched/completion.c.
 
 
 Usage:
 ------
 
-There are three parts to using completions, the initialization of the
-struct completion, the waiting part through a call to one of the variants of
-wait_for_completion() and the signaling side through a call to complete()
-or complete_all(). Further there are some helper functions for checking the
-state of completions.
+There are three main parts to using completions:
+
+ - the initialization of the 'struct completion' synchronization object
+ - the waiting part through a call to one of the variants of wait_for_completion(),
+ - the signaling side through a call to complete() or complete_all().
+
+There are also some helper functions for checking the state of completions.
+Note that while initialization must happen first, the waiting and signaling
+part can happen in any order. I.e. it's entirely normal for a thread
+to have marked a completion as 'done' before another thread checks whether
+it has to wait for it.
 
-To use completions one needs to include <linux/completion.h> and
-create a variable of type struct completion. The structure used for
-handling of completions is:
+To use completions you need to #include <linux/completion.h> and
+create a static or dynamic variable of type 'struct completion',
+which has only two fields:
 
 	struct completion {
 		unsigned int done;
 		wait_queue_head_t wait;
 	};
 
-providing the wait queue to place tasks on for waiting and the flag for
-indicating the state of affairs.
+This provides the ->wait waitqueue to place tasks on for waiting (if any), and
+the ->done completion flag for indicating whether it's completed or not.
 
-Completions should be named to convey the intent of the waiter. A good
-example is:
+Completions should be named to refer to the event that is being synchronized on.
+A good example is:
 
 	wait_for_completion(&early_console_added);
 
 	complete(&early_console_added);
 
-Good naming (as always) helps code readability.
+Good, intuitive naming (as always) helps code readability. Naming a completion
+'complete' is not helpful unless the purpose is super obvious...
 
 
 Initializing completions:

-Initialization of dynamically allocated completions, often embedded in
-other structures, is done with:
+Dynamically allocated completion objects should preferably be embedded in data
+structures that are assured to be alive for the life-time of the function/driver,
+to prevent races with asynchronous complete() calls from occurring.
+
+Particular care should be taken when using the _timeout() or _killable()/_interruptible()
+variants of wait_for_completion(), as it must be assured that memory de-allocation
+does not happen until all related activities (complete() or reinit_completion())
+have taken place, even if these wait functions return prematurely due to a timeout
+or a signal triggering.
+
+Initializing of dynamically allocated completion objects is done via a call to
+init_completion():
 
-	void init_completion(&done);
+	init_completion(&dynamic_object->done);
 
-Initialization is accomplished by initializing the wait queue and setting
-the default state to "not available", that is, "done" is set to 0.
+In this call we initialize the waitqueue and set ->done to 0, i.e. "not completed"
+or "not done".
 
 The re-initialization function, reinit_completion(), simply resets the
-done element to "not available", thus again to 0, without touching the
-wait queue. Calling init_completion() twice on the same completion object is
+->done field to 0 ("not done"), without touching the waitqueue.
+Callers of this function must make sure that there are no racy
+wait_for_completion() calls going on in parallel.
+
+Calling init_completion() on the same completion object twice is
 most likely a bug as it re-initializes the queue to an empty queue and
-enqueued tasks could get "lost" - use reinit_completion() in that case.
+enqueued tasks could get "lost" - use reinit_completion() in that case,
+but be aware of other races.
+
+For static declaration and initialization, macros are available.
+
+For static (or global) declarations in file scope you can use DECLARE_COMPLETION():
 
-For static declaration and initialization, macros are available. These are:
+	static DECLARE_COMPLETION(setup_done);
+	DECLARE_COMPLETION(setup_done);
 
-	static DECLARE_COMPLETION(setup_done)
+Note that in this case the completion is boot time (or module load time)
+initialized to 'not done' and doesn't require an init_completion() call.
 
-used for static declarations in file scope. Within functions the static
-initialization should always use:
+When a completion is declared as a local variable within a function,
+then the initialization should always use DECLARE_COMPLETION_ONSTACK()
+explicitly, not just to make lockdep happy, but also to make it clear
+that limited scope had been considered and is intentional:
 
 	DECLARE_COMPLETION_ONSTACK(setup_done)
 
-suitable for automatic/local variables on the stack and will make lockdep
-happy. Note also that one needs to make *sure* the completion passed to
-work threads remains in-scope, and no references remain to on-stack data
-when the initiating function returns.
+Note that when using completion objects as local variables you must be
+acutely aware of the short life time of the function stack: the function
+must not return to a calling context until all activities (such as waiting
+threads) have ceased and the completion object is completely unused.
 
-Using on-stack completions for code that calls any of the _timeout or
-_interruptible/_killable variants is not advisable as they will require
-additional synchronization to prevent the on-stack completion object in
-the timeout/signal cases from going out of scope. Consider using dynamically
-allocated completions when intending to use the _interruptible/_killable
-or _timeout variants of wait_for_completion().
+To emphasise this again: in particular when using some of the waiting API variants
+with more complex outcomes, such as the timeout or signalling (_timeout(),
+_killable() and _interruptible()) variants, the wait might complete
+prematurely while the object might still be in use by another thread - and a return
+from the wait_on_completion*() caller function will deallocate the function
+stack and cause subtle data corruption if a complete() is done in some
+other thread. Simple testing might not trigger these kinds of races.
 
+If unsure, use dynamically allocated completion objects, preferably embedded
+in some other long lived object that has a boringly long life time which
+exceeds the life time of any helper threads using the completion object,
+or has a lock or other synchronization mechanism to make sure complete()
+is not called on a freed object.
+
+A naive DECLARE_COMPLETION() on the stack triggers a lockdep warning.
 
 Waiting for completions:
 ------------------------
 
-For a thread of execution to wait for some concurrent work to finish, it
-calls wait_for_completion() on the initialized completion structure.
+For a thread to wait for some concurrent activity to finish, it
+calls wait_for_completion() on the initialized completion structure:
+
+	void wait_for_completion(struct completion *done)

-	wait_for_completion(&setup_done);         complete(setup_done)
+	wait_for_completion(&setup_done);	complete(setup_done);

+Notes:
+
+ - Negative addresses such as "-23 TB" are absolute addresses in bytes, counted down
+   from the top of the 64-bit address space. It's easier to understand the layout
+   when seen both in absolute addresses and in distance-from-top notation.
+
+   For example 0xffffe90000000000 == -23 TB, it's 23 TB lower than the top of the
+   64-bit address space (ffffffffffffffff).
+
+   Note that as we get closer to the top of the address space, the notation changes
+   from TB to GB and then MB/KB.
+
+ - "16M TB" might look weird at first sight, but it's an easier to visualize size
+   notation than "16 EB", which few will recognize at first sight as 16 exabytes.
+   It also shows it nicely how incredibly large 64-bit address space is.

-Section 2 - Scope.
-
-    a. License grant.
-
-        1. Subject to the terms and conditions of this Public License, the
-           Licensor hereby grants You a worldwide, royalty-free,
-           non-sublicensable, non-exclusive, irrevocable license to
-           exercise the Licensed Rights in the Licensed Material to:
-
-            A. reproduce and Share the Licensed Material, in whole or in part; and
-
-            B. produce, reproduce, and Share Adapted Material.
-
-        2. Exceptions and Limitations. For the avoidance of doubt, where
-           Exceptions and Limitations apply to Your use, this Public
-           License does not apply, and You do not need to comply with its
-           terms and conditions.
-
-        3. Term. The term of this Public License is specified in Section 6(a).
-
-        4. Media and formats; technical modifications allowed. The Licensor
-           authorizes You to exercise the Licensed Rights in all media and
-           formats whether now known or hereafter created, and to make
-           technical modifications necessary to do so. The Licensor waives
-           and/or agrees not to assert any right or authority to forbid You
-           from making technical modifications necessary to exercise the
-           Licensed Rights, including technical modifications necessary to
-           circumvent Effective Technological Measures. For purposes of
-           this Public License, simply making modifications authorized by
-           this Section 2(a)(4) never produces Adapted Material.
-
-        5. Downstream recipients.
-
-            A. Offer from the Licensor - Licensed Material. Every recipient
-               of the Licensed Material automatically receives an offer
-               from the Licensor to exercise the Licensed Rights under the
-               terms and conditions of this Public License.
-
-            B. Additional offer from the Licensor - Adapted Material. Every
-               recipient of Adapted Material from You automatically
-               receives an offer from the Licensor to exercise the Licensed
-               Rights in the Adapted Material under the conditions of the
-               Adapter's License You apply.
-
-            C. No downstream restrictions. You may not offer or impose any
-               additional or different terms or conditions on, or apply any
-               Effective Technological Measures to, the Licensed Material
-               if doing so restricts exercise of the Licensed Rights by any
-               recipient of the Licensed Material.
-
-        6. No endorsement. Nothing in this Public License constitutes or
-           may be construed as permission to assert or imply that You are,
-           or that Your use of the Licensed Material is, connected with, or
-           sponsored, endorsed, or granted official status by, the Licensor
-           or others designated to receive attribution as provided in
-           Section 3(a)(1)(A)(i).
-
-    b. Other rights.
-
-        1. Moral rights, such as the right of integrity, are not licensed
-           under this Public License, nor are publicity, privacy, and/or
-           other similar personality rights; however, to the extent
-           possible, the Licensor waives and/or agrees not to assert any
-           such rights held by the Licensor to the limited extent necessary
-           to allow You to exercise the Licensed Rights, but not otherwise.
-
-        2. Patent and trademark rights are not licensed under this Public
-           License.
-
-        3. To the extent possible, the Licensor waives any right to collect
-           royalties from You for the exercise of the Licensed Rights,
-           whether directly or through a collecting society under any
-           voluntary or waivable statutory or compulsory licensing
-           scheme. In all other cases the Licensor expressly reserves any
-           right to collect such royalties.
-
-Section 3 - License Conditions.
-
-Your exercise of the Licensed Rights is expressly made subject to the
-following conditions.
-
-    a. Attribution.

-            License, and include the text of, or the URI or hyperlink to,
-            this Public License.
-
-        2. You may satisfy the conditions in Section 3(a)(1) in any
-           reasonable manner based on the medium, means, and context in
-           which You Share the Licensed Material. For example, it may be
-           reasonable to satisfy the conditions by providing a URI or
-           hyperlink to a resource that includes the required information.
-
-        3. If requested by the Licensor, You must remove any of the
-           information required by Section 3(a)(1)(A) to the extent
-           reasonably practicable.  b. ShareAlike.In addition to the
-           conditions in Section 3(a), if You Share Adapted Material You
-           produce, the following conditions also apply.
-
-           1. The Adapter's License You apply must be a Creative Commons
-              license with the same License Elements, this version or
-              later, or a BY-SA Compatible License.
-
-           2. You must include the text of, or the URI or hyperlink to, the
-              Adapter's License You apply. You may satisfy this condition
-              in any reasonable manner based on the medium, means, and
-              context in which You Share Adapted Material.
-
-           3. You may not offer or impose any additional or different terms
-              or conditions on, or apply any Effective Technological
-              Measures to, Adapted Material that restrict exercise of the
-              rights granted under the Adapter's License You apply.
-
-Section 4 - Sui Generis Database Rights.
-
-Where the Licensed Rights include Sui Generis Database Rights that apply to
-Your use of the Licensed Material:
-
-    a. for the avoidance of doubt, Section 2(a)(1) grants You the right to
-       extract, reuse, reproduce, and Share all or a substantial portion of
-       the contents of the database;
-
-    b. if You include all or a substantial portion of the database contents
-       in a database in which You have Sui Generis Database Rights, then
-       the database in which You have Sui Generis Database Rights (but not
-       its individual contents) is Adapted Material, including for purposes
-       of Section 3(b); and
-
-    c. You must comply with the conditions in Section 3(a) if You Share all
-       or a substantial portion of the contents of the database.

-    Rights include other Copyright and Similar Rights.
-
-Section 5 - Disclaimer of Warranties and Limitation of Liability.
-
-    a. Unless otherwise separately undertaken by the Licensor, to the
-       extent possible, the Licensor offers the Licensed Material as-is and
-       as-available, and makes no representations or warranties of any kind
-       concerning the Licensed Material, whether express, implied,
-       statutory, or other. This includes, without limitation, warranties
-       of title, merchantability, fitness for a particular purpose,
-       non-infringement, absence of latent or other defects, accuracy, or
-       the presence or absence of errors, whether or not known or
-       discoverable. Where disclaimers of warranties are not allowed in

-       consequential, punitive, exemplary, or other losses, costs,
-       expenses, or damages arising out of this Public License or use of
-       the Licensed Material, even if the Licensor has been advised of the
-       possibility of such losses, costs, expenses, or damages. Where a
-       limitation of liability is not allowed in full or in part, this
-       limitation may not apply to You.
-
-    c. The disclaimer of warranties and limitation of liability provided

-       most closely approximates an absolute disclaimer and waiver of all
-       liability.
-
-Section 6 - Term and Termination.
-
-    a. This Public License applies for the term of the Copyright and
-       Similar Rights licensed here. However, if You fail to comply with

-        1. automatically as of the date the violation is cured, provided it
-           is cured within 30 days of Your discovery of the violation; or
-
-        2. upon express reinstatement by the Licensor.
-
-    c. For the avoidance of doubt, this Section 6(b) does not affect any
-       right the Licensor may have to seek remedies for Your violations of

-
-    d. For the avoidance of doubt, the Licensor may also offer the Licensed
-       Material under separate terms or conditions or stop distributing the
-       Licensed Material at any time; however, doing so will not terminate
-       this Public License.

-
-Section 7 - Other Terms and Conditions.
-

-       or conditions communicated by You unless expressly agreed.

-
-    a. For the avoidance of doubt, this Public License does not, and shall
-       not be interpreted to, reduce, limit, restrict, or impose conditions
-       on any use of the Licensed Material that could lawfully be made
-       without permission under this Public License.
-
-    b. To the extent possible, if any provision of this Public License is
-       deemed unenforceable, it shall be automatically reformed to the
-       minimum extent necessary to make it enforceable. If the provision
-       cannot be reformed, it shall be severed from this Public License
-       without affecting the enforceability of the remaining terms and
-       conditions.
-
-    c. No term or condition of this Public License will be waived and no
-       failure to comply consented to unless expressly agreed to by the
-       Licensor.
-
-    d. Nothing in this Public License constitutes or may be interpreted as
-       a limitation upon, or waiver of, any privileges and immunities that
-       apply to the Licensor or You, including from the legal processes of
-       any jurisdiction or authority.

- *	TLB Management
- *	==============
+ *	TLB Invalidation
+ *	================
  *
- *	The TLB specific code is expected to perform whatever tests it needs
- *	to determine if it should invalidate the TLB for each call.  Start
- *	addresses are inclusive and end addresses are exclusive; it is safe to
- *	round these addresses down.
+ * 	This header file implements the low-level TLB invalidation routines
+ *	(sometimes referred to as "flushing" in the kernel) for arm64.
  *
- *	flush_tlb_all()
+ *	Every invalidation operation uses the following template:
+ *
+ *	DSB ISHST	// Ensure prior page-table updates have completed
+ *	TLBI ...	// Invalidate the TLB
+ *	DSB ISH		// Ensure the TLB invalidation has completed
+ *      if (invalidated kernel mappings)
+ *		ISB	// Discard any instructions fetched from the old mapping
+ *
+ *
+ *	The following functions form part of the "core" TLB invalidation API,
+ *	as documented in Documentation/core-api/cachetlb.rst:
  *
- *		Invalidate the entire TLB.
+ *	flush_tlb_all()
+ *		Invalidate the entire TLB (kernel + user) on all CPUs
  *
  *	flush_tlb_mm(mm)
+ *		Invalidate an entire user address space on all CPUs.
+ *		The 'mm' argument identifies the ASID to invalidate.
+ *
+ *	flush_tlb_range(vma, start, end)
+ *		Invalidate the virtual-address range '[start, end)' on all
+ *		CPUs for the user address space corresponding to 'vma->mm'.
+ *		Note that this operation also invalidates any walk-cache
+ *		entries associated with translations for the specified address
+ *		range.
+ *
+ *	flush_tlb_kernel_range(start, end)
+ *		Same as flush_tlb_range(..., start, end), but applies to
+ * 		kernel mappings rather than a particular user address space.
+ *		Whilst not explicitly documented, this function is used when
+ *		unmapping pages from vmalloc/io space.
+ *
+ *	flush_tlb_page(vma, addr)
+ *		Invalidate a single user mapping for address 'addr' in the
+ *		address space corresponding to 'vma->mm'.  Note that this
+ *		operation only invalidates a single, last-level page-table
+ *		entry and therefore does not affect any walk-caches.
  *
- *		Invalidate all TLB entries in a particular address space.
- *		- mm	- mm_struct describing address space
  *
- *	flush_tlb_range(mm,start,end)
+ *	Next, we have some undocumented invalidation routines that you probably
+ *	don't want to call unless you know what you're doing:
  *
- *		Invalidate a range of TLB entries in the specified address
- *		space.
- *		- mm	- mm_struct describing address space
- *		- start - start address (may not be aligned)
- *		- end	- end address (exclusive, may not be aligned)
+ *	local_flush_tlb_all()
+ *		Same as flush_tlb_all(), but only applies to the calling CPU.
  *
- *	flush_tlb_page(vaddr,vma)
+ *	__flush_tlb_kernel_pgtable(addr)
+ *		Invalidate a single kernel mapping for address 'addr' on all
+ *		CPUs, ensuring that any walk-cache entries associated with the
+ *		translation are also invalidated.
  *
- *		Invalidate the specified page in the specified address range.
- *		- vaddr - virtual address (may not be aligned)
- *		- vma	- vma_struct describing address range
+ *	__flush_tlb_range(vma, start, end, stride, last_level)
+ *		Invalidate the virtual-address range '[start, end)' on all
+ *		CPUs for the user address space corresponding to 'vma->mm'.
+ *		The invalidation operations are issued at a granularity
+ *		determined by 'stride' and only affect any walk-cache entries
+ *		if 'last_level' is equal to false.
  *
- *	flush_kern_tlb_page(kaddr)
  *
- *		Invalidate the TLB entry for the specified page.  The address
- *		will be in the kernels virtual memory space.  Current uses
- *		only require the D-TLB to be invalidated.
- *		- kaddr - Kernel virtual memory address
+ *	Finally, take a look at asm/tlb.h to see how tlb_flush() is implemented
+ *	on top of these routines, since that is our interface to the mmu_gather
+ *	API as used by munmap() and friends.

+ * @paranoid: 		non-zero means that this vector may be invoked from

+ *			2 is special -- see below.
+ * @shift_ist:		Set to an IST index if entries from kernel mode should
+ *             		decrement the IST stack so that nested entries get a
+ *			fresh stack.  (This is for #DB, which has a nasty habit
+ *             		of recursing.)
+ *
+ * idtentry generates an IDT stub that sets up a usable kernel context,
+ * creates struct pt_regs, and calls @do_sym.  The stub has the following
+ * special behaviors:
+ *
+ * On an entry from user mode, the stub switches from the trampoline or
+ * IST stack to the normal thread stack.  On an exit to user mode, the
+ * normal exit-to-usermode path is invoked.
+ *
+ * On an exit to kernel mode, if @paranoid == 0, we check for preemption,
+ * whereas we omit the preemption check if @paranoid != 0.  This is purely
+ * because the implementation is simpler this way.  The kernel only needs
+ * to check for asynchronous kernel preemption when IRQ handlers return.
+ *
+ * If @paranoid == 0, then the stub will handle IRET faults by pretending
+ * that the fault came from user mode.  It will handle gs_change faults by
+ * pretending that the fault happened with kernel GSBASE.  Since this handling
+ * is omitted for @paranoid != 0, the #GP, #SS, and #NP stubs must have
+ * @paranoid == 0.  This special handling will do the wrong thing for
+ * espfix-induced #DF on IRET, so #DF must not use @paranoid == 0.
+ *
+ * @paranoid == 2 is special: the stub will never switch stacks.  This is for
+ * #DF: if the thread stack is somehow unusable, we'll still get a useful OOPS.

+ *
+ *    This function takes care of setting up using auto suspend for the device,
+ *    the autosuspend delay is set to -1 to make runtime suspend impossible
+ *    until an updated value is either set by user or by driver. Drivers do

-	  Support for diskonchip G4 nand flash, found in various smartphones and
-	  PDAs, among them the Palm Treo680, HTC Prophet and Wizard, Toshiba
-	  Portege G900, Asus P526, and O2 XDA Zinc.
-
-	  With this driver you will be able to use UBI and create a ubifs on the
-	  device, so you may wish to consider enabling UBI and UBIFS as well.
-
-	  These devices ship with the Mys/Sandisk SAFTL formatting, for which
-	  there is currently no mtd parser, so you may want to use command line
-	  partitioning to segregate write-protected blocks. On the Treo680, the
-	  first five erase blocks (256KiB each) are write-protected, followed
-	  by the block containing the saftl partition table.  This is probably
-	  typical.

-	 * This requires us to convert addresses passed by the mtd nand
-	 * infrastructure code to those used by the device.
-	 *
-	 * The address that is written to the device consists of four bytes: the
-	 * first two are the 2k page number, and the second is the index into
-	 * the page.  The index is in terms of 16-bit half-words and includes

  * Copyright (C) 2017 Marvell
  * Author: Miquel RAYNAL <miquel.raynal@free-electrons.com>
  *
+ *
+ * This NAND controller driver handles two versions of the hardware,
+ * one is called NFCv1 and is available on PXA SoCs and the other is
+ * called NFCv2 and is available on Armada SoCs.
+ *
+ * The main visible difference is that NFCv1 only has Hamming ECC
+ * capabilities, while NFCv2 also embeds a BCH ECC engine. Also, DMA
+ * is not used with NFCv2.
+ *
+ * The ECC layouts are depicted in details in Marvell AN-379, but here
+ * is a brief description.
+ *
+ * When using Hamming, the data is split in 512B chunks (either 1, 2
+ * or 4) and each chunk will have its own ECC "digest" of 6B at the
+ * beginning of the OOB area and eventually the remaining free OOB
+ * bytes (also called "spare" bytes in the driver). This engine
+ * corrects up to 1 bit per chunk and detects reliably an error if
+ * there are at most 2 bitflips. Here is the page layout used by the
+ * controller when Hamming is chosen:
+ *
+ * +-------------------------------------------------------------+
+ * | Data 1 | ... | Data N | ECC 1 | ... | ECCN | Free OOB bytes |
+ * +-------------------------------------------------------------+
+ *
+ * When using the BCH engine, there are N identical (data + free OOB +
+ * ECC) sections and potentially an extra one to deal with
+ * configurations where the chosen (data + free OOB + ECC) sizes do
+ * not align with the page (data + OOB) size. ECC bytes are always
+ * 30B per ECC chunk. Here is the page layout used by the controller
+ * when BCH is chosen:
+ *
+ * +-----------------------------------------
+ * | Data 1 | Free OOB bytes 1 | ECC 1 | ...
+ * +-----------------------------------------
+ *
+ *      -------------------------------------------
+ *       ... | Data N | Free OOB bytes N | ECC N |
+ *      -------------------------------------------
+ *
+ *           --------------------------------------------+
+ *            Last Data | Last Free OOB bytes | Last ECC |
+ *           --------------------------------------------+
+ *
+ * In both cases, the layout seen by the user is always: all data
+ * first, then all free OOB bytes and finally all ECC bytes. With BCH,
+ * ECC bytes are 30B long and are padded with 0xFF to align on 32
+ * bytes.
+ *
+ * The controller has certain limitations that are handled by the
+ * driver:
+ *   - It can only read 2k at a time. To overcome this limitation, the
+ *     driver issues data cycles on the bus, without issuing new
+ *     CMD + ADDR cycles. The Marvell term is "naked" operations.
+ *   - The ECC strength in BCH mode cannot be tuned. It is fixed 16
+ *     bits. What can be tuned is the ECC block size as long as it
+ *     stays between 512B and 2kiB. It's usually chosen based on the
+ *     chip ECC requirements. For instance, using 2kiB ECC chunks
+ *     provides 4b/512B correctability.
+ *   - The controller will always treat data bytes, free OOB bytes
+ *     and ECC bytes in that order, no matter what the real layout is
+ *     (which is usually all data then all OOB bytes). The
+ *     marvell_nfc_layouts array below contains the currently
+ *     supported layouts.
+ *   - Because of these weird layouts, the Bad Block Markers can be
+ *     located in data section. In this case, the NAND_BBT_NO_OOB_BBM
+ *     option must be set to prevent scanning/writing bad block
+ *     markers.

+ * @hw: pointer to the hw struct

+ * This function enables/disables the FW logging via Rx CQ events and a UART
+ * port based on predetermined configurations. FW logging via the Rx CQ can be
+ * enabled/disabled for individual PF's. However, FW logging via the UART can
+ * only be enabled/disabled for all PFs on the same device.
+ *
+ * To enable overall FW logging, the "cq_en" and "uart_en" enable bits in
+ * hw->fw_log need to be set accordingly, e.g. based on user-provided input,
+ * before initializing the device.
+ *
+ * When re/configuring FW logging, callers need to update the "cfg" elements of
+ * the hw->fw_log.evnts array with the desired logging event configurations for
+ * modules of interest. When disabling FW logging completely, the callers can
+ * just pass false in the "enable" parameter. On completion, the function will
+ * update the "cur" element of the hw->fw_log.evnts array with the resulting
+ * logging event configurations of the modules that are being re/configured. FW
+ * logging modules that are not part of a reconfiguration operation retain their
+ * previous states.
+ *
+ * Before resetting the device, it is recommended that the driver disables FW
+ * logging before shutting down the control queue. When disabling FW logging
+ * ("enable" = false), the latest configurations of FW logging events stored in
+ * hw->fw_log.evnts[] are not overridden to allow them to be reconfigured after
+ * a device reset.
+ *
+ * When enabling FW logging to emit log messages via the Rx CQ during the
+ * device's initialization phase, a mechanism alternative to interrupt handlers
+ * needs to be used to extract FW log messages from the Rx CQ periodically and
+ * to prevent the Rx CQ from being full and stalling other types of control
+ * messages from FW to SW. Interrupts are typically disabled during the device's
+ * initialization phase.

- * ccio-rm-dma.c:
- *	DMA management routines for first generation cache-coherent machines.
- *	"Real Mode" operation refers to U2/Uturn chip operation. The chip
- *      can perform coherency checks w/o using the I/O MMU. That's all we
- *      need until support for more than 4GB phys mem is needed.
- * 
- *	This is the trivial case - basically what x86 does.
- *
- *	Drawbacks of using Real Mode are:
- *	o outbound DMA is slower since one isn't using the prefetching
- *	  U2 can do for outbound DMA.
- *	o Ability to do scatter/gather in HW is also lost.
- *      o only known to work with PCX-W processor. (eg C360)
- *        (PCX-U/U+ are not coherent with U2 in real mode.)

+Contributions are solicited in particular to remedy the following issues:
+
+cpcihp:
+
+* There are no implementations of the ->hardware_test, ->get_power and
+  ->set_power callbacks in struct cpci_hp_controller_ops.  Why were they
+  introduced?  Can they be removed from the struct?
+
+cpqphp:
+
+* The driver spawns a kthread cpqhp_event_thread() which is woken by the
+  hardirq handler cpqhp_ctrl_intr().  Convert this to threaded IRQ handling.
+  The kthread is also woken from the timer pushbutton_helper_thread(),
+  convert it to call irq_wake_thread().  Use pciehp as a template.
+
+* A large portion of cpqphp_ctrl.c and cpqphp_pci.c concerns resource
+  management.  Doesn't this duplicate functionality in the core?
+
+ibmphp:
+
+* Implementations of hotplug_slot_ops callbacks such as get_adapter_present()
+  in ibmphp_core.c create a copy of the struct slot on the stack, then perform
+  the actual operation on that copy.  Determine if this overhead is necessary,
+  delete it if not.  The functions also perform a NULL pointer check on the
+  struct hotplug_slot, this seems superfluous.
+
+* Several functions access the pci_slot member in struct hotplug_slot even
+  though pci_hotplug.h declares it private.  See get_max_bus_speed() for an
+  example.  Either the pci_slot member should no longer be declared private
+  or ibmphp should store a pointer to its bus in struct slot.  Probably the
+  former.
+
+* The functions get_max_adapter_speed() and get_bus_name() are commented out.
+  Can they be deleted?  There are also forward declarations at the top of
+  ibmphp_core.c as well as pointers in ibmphp_hotplug_slot_ops, likewise
+  commented out.
+
+* ibmphp_init_devno() takes a struct slot **, it could instead take a
+  struct slot *.
+
+* The return value of pci_hp_register() is not checked.
+
+* iounmap(io_mem) is called in the error path of ebda_rsrc_controller()
+  and once more in the error path of its caller ibmphp_access_ebda().
+
+* The various slot data structures are difficult to follow and need to be
+  simplified.  A lot of functions are too large and too complex, they need
+  to be broken up into smaller, manageable pieces.  Negative examples are
+  ebda_rsrc_controller() and configure_bridge().
+
+* A large portion of ibmphp_res.c and ibmphp_pci.c concerns resource
+  management.  Doesn't this duplicate functionality in the core?
+
+sgi_hotplug:
+
+* Several functions access the pci_slot member in struct hotplug_slot even
+  though pci_hotplug.h declares it private.  See sn_hp_destroy() for an
+  example.  Either the pci_slot member should no longer be declared private
+  or sgi_hotplug should store a pointer to it in struct slot.  Probably the
+  former.
+
+shpchp:
+
+* There is only a single implementation of struct hpc_ops.  Can the struct be
+  removed and its functions invoked directly?  This has already been done in
+  pciehp with commit 82a9e79ef132 ("PCI: pciehp: remove hpc_ops").  Clarify
+  if there was a specific reason not to apply the same change to shpchp.
+
+* The ->get_mode1_ECC_cap callback in shpchp_hpc_ops is never invoked.
+  Why was it introduced?  Can it be removed?
+
+* The hardirq handler shpc_isr() queues events on a workqueue.  It can be
+  simplified by converting it to threaded IRQ handling.  Use pciehp as a
+  template.

+ * The hardware manual describes two levels of multiplexing, but it's more

+ * the multiplexing for Ethernet MDIO signals.
+ *
+ * Level 1 functions go from 0 to 9, with level 1 function '15' (0xf) specifying
+ * that level 2 functions are used instead. Level 2 has a lot more options,
+ * going from 0 to 61. Level 3 allows selection of MDIO functions which can be
+ * floating, or one of seven internal peripherals. Unfortunately, there are two
+ * level 2 functions that can select MDIO, and two MDIO channels so we have four
+ * sets of level 3 functions.
+ *
+ * For this driver, we've compounded the numbers together, so:
+ *    0 to   9 is level 1
+ *   10 to  71 is 10 + level 2 number
+ *   72 to  79 is 72 + MDIO0 source for level 2 MDIO function.
+ *   80 to  87 is 80 + MDIO0 source for level 2 MDIO_E1 function.
+ *   88 to  95 is 88 + MDIO1 source for level 2 MDIO function.
+ *   96 to 103 is 96 + MDIO1 source for level 2 MDIO_E1 function.
+ * Examples:
+ *  Function 28 corresponds UART0
+ *  Function 73 corresponds to MDIO0 to GMAC0

-* refine README file

 This is a list of things that need to be done to get this driver out of the
 staging directory.
+
+- Implement the gasket framework's functionality through UIO instead of
+  introducing a new user-space drivers framework that is quite similar.
+
+  UIO provides the necessary bits to implement user-space drivers. Meanwhile
+  the gasket APIs adds some extra conveniences like PCI BAR mapping, and
+  MSI interrupts. Add these features to the UIO subsystem, then re-implement
+  the Apex driver as a basic UIO driver instead (include/linux/uio_driver.h)
+
 - Document sysfs files with Documentation/ABI/ entries.
+
 - Use misc interface instead of major number for driver version description.
+
 - Add descriptions of module_param's
+
 - apex_get_status() should actually check status.
+
 - "drivers" should never be dealing with "raw" sysfs calls or mess around with
   kobjects at all. The driver core should handle all of this for you
   automaically. There should not be a need for raw attribute macros.

+ * Pending cluster reservations for bigalloc file systems
+ *
+ * A cluster with a pending reservation is a logical cluster shared by at
+ * least one extent in the extents status tree with delayed and unwritten
+ * status and at least one other written or unwritten extent.  The
+ * reservation is said to be pending because a cluster reservation would
+ * have to be taken in the event all blocks in the cluster shared with
+ * written or unwritten extents were deleted while the delayed and
+ * unwritten blocks remained.
+ *
+ * The set of pending cluster reservations is an auxiliary data structure
+ * used with the extents status tree to implement reserved cluster/block
+ * accounting for bigalloc file systems.  The set is kept in memory and
+ * records all pending cluster reservations.
+ *
+ * Its primary function is to avoid the need to read extents from the
+ * disk when invalidating pages as a result of a truncate, punch hole, or
+ * collapse range operation.  Page invalidation requires a decrease in the
+ * reserved cluster count if it results in the removal of all delayed
+ * and unwritten extents (blocks) from a cluster that is not shared with a
+ * written or unwritten extent, and no decrease otherwise.  Determining
+ * whether the cluster is shared can be done by searching for a pending
+ * reservation on it.
+ *
+ * Secondarily, it provides a potentially faster method for determining
+ * whether the reserved cluster count should be increased when a physical
+ * cluster is deallocated as a result of a truncate, punch hole, or
+ * collapse range operation.  The necessary information is also present
+ * in the extents status tree, but might be more rapidly accessed in
+ * the pending reservation set in many cases due to smaller size.
+ *
+ * The pending cluster reservation set is implemented as a red-black tree
+ * with the goal of minimizing per page search time overhead.

+ * The VFS allows partial EOF blocks to "match" for dedupe even though it hasn't

+ * hence can introduce a corruption into the file that has it's block replaced.
+ *
+ * In similar fashion, the VFS file cloning also allows partial EOF blocks to be

+ * of the destination file, then we can expose stale data from beyond the source
+ * file EOF in the destination file.
+ *
+ * XFS doesn't support partial block sharing, so in both cases we have check
+ * these cases ourselves. For dedupe, we can simply round the length to dedupe
+ * down to the previous whole block and ignore the partial EOF block. While this
+ * means we can't dedupe the last block of a file, this is an acceptible
+ * tradeoff for simplicity on implementation.
+ *
+ * For cloning, we want to share the partial EOF block if it is also the new EOF
+ * block of the destination file. If the partial EOF block lies inside the
+ * existing destination EOF, then we have to abort the clone to avoid exposing
+ * stale data in the destination file. Hence we reject these clone attempts with

+ *
+ * Just as shown below, the link-list pointer register will be pointed to the
+ * physical address of 'configuration 1', and the 'configuration 1' link-list
+ * pointer will be pointed to 'configuration 2', and so on.
+ * Once trigger the DMA transfer, the DMA controller will load 'configuration
+ * 1' to its registers automatically, after 'configuration 1' transaction is
+ * done, DMA controller will load 'configuration 2' automatically, until all
+ * DMA transactions are done.
+ *
+ * Note: The last link-list pointer should point to the physical address
+ * of 'configuration 1', which can avoid DMA controller loads incorrect
+ * configuration when the last configuration transaction is done.

+ *                         `len' to the max attribute number.
+ *                         Note that nla_parse() will validate, but of course not
+ *                         parse, the nested sub-policies.
+ *    NLA_NESTED_ARRAY     Points to a nested policy to validate, must also set
+ *                         `len' to the max attribute number. The difference to
+ *                         NLA_NESTED is the structure - NLA_NESTED has the
+ *                         nested attributes directly inside, while an array has
+ *                         the nested attributes at another level down and the

-/* A BPF sock_map is used to store sock objects. This is primarly used

- *
- * A sock map may have BPF programs attached to it, currently a program
- * used to parse packets and a program to provide a verdict and redirect
- * decision on the packet are supported. Any programs attached to a sock
- * map are inherited by sock objects when they are added to the map. If
- * no BPF programs are attached the sock object may only be used for sock
- * redirect.
- *
- * A sock object may be in multiple maps, but can only inherit a single
- * parse or verdict program. If adding a sock object to a map would result
- * in having multiple parsing programs the update will return an EBUSY error.
- *

- * A psock is destroyed via call_rcu and after any worker threads are cancelled

- * Psocks may exist in multiple maps, but only a single set of parse/verdict

- * Rules to follow,

- *  - sk_user_data must only be modified inside sk_callback_lock and read
- *    inside RCU critical section.

- * the owner field when it unlocks. A reader, on the other hand, will
- * not touch the owner field when it unlocks.
+ * The least significant 2 bits of the owner value has the following
+ * meanings when set.
+ *  - RWSEM_READER_OWNED (bit 0): The rwsem is owned by readers
+ *  - RWSEM_ANONYMOUSLY_OWNED (bit 1): The rwsem is anonymously owned,
+ *    i.e. the owner(s) cannot be readily determined. It can be reader
+ *    owned or the owning writer is indeterminate.
  *
- * In essence, the owner field now has the following 4 states:
- *  1) 0
- *     - lock is free or the owner hasn't set the field yet
- *  2) RWSEM_READER_OWNED
- *     - lock is currently or previously owned by readers (lock is free
- *       or not set by owner yet)
- *  3) RWSEM_ANONYMOUSLY_OWNED bit set with some other bits set as well
- *     - lock is owned by an anonymous writer, so spinning on the lock
- *       owner should be disabled.
- *  4) Other non-zero value
- *     - a writer owns the lock and other writers can spin on the lock owner.
+ * When a writer acquires a rwsem, it puts its task_struct pointer
+ * into the owner field. It is cleared after an unlock.
+ *
+ * When a reader acquires a rwsem, it will also puts its task_struct
+ * pointer into the owner field with both the RWSEM_READER_OWNED and
+ * RWSEM_ANONYMOUSLY_OWNED bits set. On unlock, the owner field will
+ * largely be left untouched. So for a free or reader-owned rwsem,
+ * the owner value may contain information about the last reader that
+ * acquires the rwsem. The anonymous bit is set because that particular
+ * reader may or may not still own the lock.
+ *
+ * That information may be helpful in debugging cases where the system
+ * seems to hang on a reader owned rwsem especially if only one reader

+DESCRIPTION
+===========
+	**bpftool net { show | list } [ dev name ]**
+                  List bpf program attachments in the kernel networking subsystem.
+
+                  Currently, only device driver xdp attachments and tc filter
+                  classification/action attachments are implemented, i.e., for
+                  program types **BPF_PROG_TYPE_SCHED_CLS**,
+                  **BPF_PROG_TYPE_SCHED_ACT** and **BPF_PROG_TYPE_XDP**.
+                  For programs attached to a particular cgroup, e.g.,
+                  **BPF_PROG_TYPE_CGROUP_SKB**, **BPF_PROG_TYPE_CGROUP_SOCK**,
+                  **BPF_PROG_TYPE_SOCK_OPS** and **BPF_PROG_TYPE_CGROUP_SOCK_ADDR**,
+                  users can use **bpftool cgroup** to dump cgroup attachments.
+                  For sk_{filter, skb, msg, reuseport} and lwt/seg6
+                  bpf programs, users should consult other tools, e.g., iproute2.
+
+                  The current output will start with all xdp program attachments, followed by
+                  all tc class/qdisc bpf program attachments. Both xdp programs and
+                  tc programs are ordered based on ifindex number. If multiple bpf
+                  programs attached to the same networking device through **tc filter**,
+                  the order will be first all bpf programs attached to tc classes, then
+                  all bpf programs attached to non clsact qdiscs, and finally all
+                  bpf programs attached to root and clsact qdisc.
+
+	**bpftool net help**
+		  Print short help message.
+
+OPTIONS
+=======
+	-h, --help
+		  Print short generic help message (similar to **bpftool help**).
+
+	-v, --version
+		  Print version number (similar to **bpftool version**).
+
+	-j, --json
+		  Generate JSON output. For commands that cannot produce JSON, this
+		  option has no effect.
+
+	-p, --pretty
+		  Generate human-readable JSON output. Implies **-j**.

+ * Contract with kernel for walking the perf ring buffer from
+ * user space requires the following barrier pairing (quote
+ * from kernel/events/ring_buffer.c):
+ *
+ *   Since the mmap() consumer (userspace) can run on a
+ *   different CPU:
+ *
+ *   kernel                             user
+ *
+ *   if (LOAD ->data_tail) {            LOAD ->data_head
+ *                      (A)             smp_rmb()       (C)
+ *      STORE $data                     LOAD $data
+ *      smp_wmb()       (B)             smp_mb()        (D)
+ *      STORE ->data_head               STORE ->data_tail
+ *   }
+ *
+ *   Where A pairs with D, and B pairs with C.
+ *
+ *   In our case A is a control dependency that separates the
+ *   load of the ->data_tail and the stores of $data. In case
+ *   ->data_tail indicates there is no room in the buffer to
+ *   store $data we do not.
+ *
+ *   D needs to be a full barrier since it separates the data
+ *   READ from the tail WRITE.
+ *
+ *   For B a WMB is sufficient since it separates two WRITEs,
+ *   and for C an RMB is sufficient since it separates two READs.
+ *
+ * Note, instead of B, C, D we could also use smp_store_release()
+ * in B and D as well as smp_load_acquire() in C.
+ *
+ * However, this optimization does not make sense for all kernel
+ * supported architectures since for a fair number it would
+ * resolve into READ_ONCE() + smp_mb() pair for smp_load_acquire(),
+ * and smp_mb() + WRITE_ONCE() pair for smp_store_release().
+ *
+ * Thus for those smp_wmb() in B and smp_rmb() in C would still
+ * be less expensive. For the case of D this has either the same
+ * cost or is less expensive, for example, due to TSO x86 can
+ * avoid the CPU barrier entirely.

+LOCKING
+-------
+
+The LKMM includes locking.  In fact, there is special code for locking
+in the formal model, added in order to make tools run faster.
+However, this special code is intended to be more or less equivalent
+to concepts we have already covered.  A spinlock_t variable is treated
+the same as an int, and spin_lock(&s) is treated almost the same as:
+
+	while (cmpxchg_acquire(&s, 0, 1) != 0)
+		cpu_relax();
+
+This waits until s is equal to 0 and then atomically sets it to 1,
+and the read part of the cmpxchg operation acts as an acquire fence.
+An alternate way to express the same thing would be:
+
+	r = xchg_acquire(&s, 1);
+
+along with a requirement that at the end, r = 0.  Similarly,
+spin_trylock(&s) is treated almost the same as:
+
+	return !cmpxchg_acquire(&s, 0, 1);
+
+which atomically sets s to 1 if it is currently equal to 0 and returns
+true if it succeeds (the read part of the cmpxchg operation acts as an
+acquire fence only if the operation is successful).  spin_unlock(&s)
+is treated almost the same as:
+
+	smp_store_release(&s, 0);
+
+The "almost" qualifiers above need some explanation.  In the LKMM, the
+store-release in a spin_unlock() and the load-acquire which forms the
+first half of the atomic rmw update in a spin_lock() or a successful
+spin_trylock() -- we can call these things lock-releases and
+lock-acquires -- have two properties beyond those of ordinary releases
+and acquires.
+
+First, when a lock-acquire reads from a lock-release, the LKMM
+requires that every instruction po-before the lock-release must
+execute before any instruction po-after the lock-acquire.  This would
+naturally hold if the release and acquire operations were on different
+CPUs, but the LKMM says it holds even when they are on the same CPU.
+For example:
+
+	int x, y;
+	spinlock_t s;
+
+	P0()
+	{
+		int r1, r2;
+
+		spin_lock(&s);
+		r1 = READ_ONCE(x);
+		spin_unlock(&s);
+		spin_lock(&s);
+		r2 = READ_ONCE(y);
+		spin_unlock(&s);
+	}
+
+	P1()
+	{
+		WRITE_ONCE(y, 1);
+		smp_wmb();
+		WRITE_ONCE(x, 1);
+	}
+
+Here the second spin_lock() reads from the first spin_unlock(), and
+therefore the load of x must execute before the load of y.  Thus we
+cannot have r1 = 1 and r2 = 0 at the end (this is an instance of the
+MP pattern).
+
+This requirement does not apply to ordinary release and acquire
+fences, only to lock-related operations.  For instance, suppose P0()
+in the example had been written as:
+
+	P0()
+	{
+		int r1, r2, r3;
+
+		r1 = READ_ONCE(x);
+		smp_store_release(&s, 1);
+		r3 = smp_load_acquire(&s);
+		r2 = READ_ONCE(y);
+	}
+
+Then the CPU would be allowed to forward the s = 1 value from the
+smp_store_release() to the smp_load_acquire(), executing the
+instructions in the following order:
+
+		r3 = smp_load_acquire(&s);	// Obtains r3 = 1
+		r2 = READ_ONCE(y);
+		r1 = READ_ONCE(x);
+		smp_store_release(&s, 1);	// Value is forwarded
+
+and thus it could load y before x, obtaining r2 = 0 and r1 = 1.
+
+Second, when a lock-acquire reads from a lock-release, and some other
+stores W and W' occur po-before the lock-release and po-after the
+lock-acquire respectively, the LKMM requires that W must propagate to
+each CPU before W' does.  For example, consider:
+
+	int x, y;
+	spinlock_t x;
+
+	P0()
+	{
+		spin_lock(&s);
+		WRITE_ONCE(x, 1);
+		spin_unlock(&s);
+	}
+
+	P1()
+	{
+		int r1;
+
+		spin_lock(&s);
+		r1 = READ_ONCE(x);
+		WRITE_ONCE(y, 1);
+		spin_unlock(&s);
+	}
+
+	P2()
+	{
+		int r2, r3;
+
+		r2 = READ_ONCE(y);
+		smp_rmb();
+		r3 = READ_ONCE(x);
+	}
+
+If r1 = 1 at the end then the spin_lock() in P1 must have read from
+the spin_unlock() in P0.  Hence the store to x must propagate to P2
+before the store to y does, so we cannot have r2 = 1 and r3 = 0.
+
+These two special requirements for lock-release and lock-acquire do
+not arise from the operational model.  Nevertheless, kernel developers
+have come to expect and rely on them because they do hold on all
+architectures supported by the Linux kernel, albeit for various
+differing reasons.

+==================
+LITMUS TEST NAMING
+==================
+
+Litmus tests are usually named based on their contents, which means that
+looking at the name tells you what the litmus test does.  The naming
+scheme covers litmus tests having a single cycle that passes through
+each process exactly once, so litmus tests not fitting this description
+are named on an ad-hoc basis.
+
+The structure of a litmus-test name is the litmus-test class, a plus
+sign ("+"), and one string for each process, separated by plus signs.
+The end of the name is ".litmus".
+
+The litmus-test classes may be found in the infamous test6.pdf:
+https://www.cl.cam.ac.uk/~pes20/ppc-supplemental/test6.pdf
+Each class defines the pattern of accesses and of the variables accessed.
+For example, if the one process writes to a pair of variables, and
+the other process reads from these same variables, the corresponding
+litmus-test class is "MP" (message passing), which may be found on the
+left-hand end of the second row of tests on page one of test6.pdf.
+
+The strings used to identify the actions carried out by each process are
+complex due to a desire to have short(er) names.  Thus, there is a tool to
+generate these strings from a given litmus test's actions.  For example,
+consider the processes from SB+rfionceonce-poonceonces.litmus:
+
+	P0(int *x, int *y)
+	{
+		int r1;
+		int r2;
+
+		WRITE_ONCE(*x, 1);
+		r1 = READ_ONCE(*x);
+		r2 = READ_ONCE(*y);
+	}
+
+	P1(int *x, int *y)
+	{
+		int r3;
+		int r4;
+
+		WRITE_ONCE(*y, 1);
+		r3 = READ_ONCE(*y);
+		r4 = READ_ONCE(*x);
+	}
+
+The next step is to construct a space-separated list of descriptors,
+interleaving descriptions of the relation between a pair of consecutive
+accesses with descriptions of the second access in the pair.
+
+P0()'s WRITE_ONCE() is read by its first READ_ONCE(), which is a
+reads-from link (rf) and internal to the P0() process.  This is
+"rfi", which is an abbreviation for "reads-from internal".  Because
+some of the tools string these abbreviations together with space
+characters separating processes, the first character is capitalized,
+resulting in "Rfi".
+
+P0()'s second access is a READ_ONCE(), as opposed to (for example)
+smp_load_acquire(), so next is "Once".  Thus far, we have "Rfi Once".
+
+P0()'s third access is also a READ_ONCE(), but to y rather than x.
+This is related to P0()'s second access by program order ("po"),
+to a different variable ("d"), and both accesses are reads ("RR").
+The resulting descriptor is "PodRR".  Because P0()'s third access is
+READ_ONCE(), we add another "Once" descriptor.
+
+A from-read ("fre") relation links P0()'s third to P1()'s first
+access, and the resulting descriptor is "Fre".  P1()'s first access is
+WRITE_ONCE(), which as before gives the descriptor "Once".  The string
+thus far is thus "Rfi Once PodRR Once Fre Once".
+
+The remainder of P1() is similar to P0(), which means we add
+"Rfi Once PodRR Once".  Another fre links P1()'s last access to
+P0()'s first access, which is WRITE_ONCE(), so we add "Fre Once".
+The full string is thus:
+
+	Rfi Once PodRR Once Fre Once Rfi Once PodRR Once Fre Once
+
+This string can be given to the "norm7" and "classify7" tools to
+produce the name:
+
+	$ norm7 -bell linux-kernel.bell \
+		Rfi Once PodRR Once Fre Once Rfi Once PodRR Once Fre Once | \
+	  sed -e 's/:.*//g'
+	SB+rfionceonce-poonceonces
+
+Adding the ".litmus" suffix: SB+rfionceonce-poonceonces.litmus
+
+The descriptors that describe connections between consecutive accesses
+within the cycle through a given litmus test can be provided by the herd
+tool (Rfi, Po, Fre, and so on) or by the linux-kernel.bell file (Once,
+Release, Acquire, and so on).
+
+To see the full list of descriptors, execute the following command:
+
+	$ diyone7 -bell linux-kernel.bell -show edges

+# A test for switch behavior under MC overload. An issue in Spectrum chips
+# causes throughput of UC traffic to drop severely when a switch is under heavy
+# MC load. This issue can be overcome by putting the switch to MC-aware mode.
+# This test verifies that UC performance stays intact even as the switch is
+# under MC flood, and therefore that the MC-aware mode is enabled and correctly
+# configured.
+#
+# Because mlxsw throttles CPU port, the traffic can't actually reach userspace
+# at full speed. That makes it impossible to use iperf3 to simply measure the
+# throughput, because many packets (that reach $h3) don't get to the kernel at
+# all even in UDP mode (the situation is even worse in TCP mode, where one can't
+# hope to see more than a couple Mbps).
+#
+# So instead we send traffic with mausezahn and use RX ethtool counters at $h3.
+# Multicast traffic is untagged, unicast traffic is tagged with PCP 1. Therefore
+# each gets a different priority and we can use per-prio ethtool counters to
+# measure the throughput. In order to avoid prioritizing unicast traffic, prio
+# qdisc is installed on $swp3 and maps all priorities to the same band #7 (and
+# thus TC 0).
+#
+# Mausezahn can't actually saturate the links unless it's using large frames.
+# Thus we set MTU to 10K on all involved interfaces. Then both unicast and
+# multicast traffic uses 8K frames.
