Our FW can support several fastpath HSI [for backward compatibility] but up
until now VFs were always configured to use latest fastpath HSI [although VF
driver might be older and use an older fastpath HSI].
For linux drivers, the differences are insignificant since driver never
utilized features that were overridden by the HSI change. But for VMs running
other operating systems this might be a problem.
In addition, eventually FW might change fastpath HSI in such a manner that
backward compatibility WILL break unless configured with proper version.
This patch fixes the issue for other operating system VMs, as well as lays
the ground work for forward compatibility in regard to the fastpath HSI.

The comment says that the built-in strncmp didn't work. That is not
surprising, as apparently "str" semantics are not really what is
wanted (hint: de4x5_strncmp only stops when two different bytes are
encountered or the end is reached; not if either byte happens to be
0). de4x5_strncmp is actually a memcmp (except for the signature and
that bytes are not necessarily treated as unsigned char); since only
the boolean value of the result is used we can just replace
de4x5_strncmp with memcmp.

commit 908344cdda80 ("tipc: fix bug in multicast congestion
handling") introduced two bugs with the bclink wakeup
function. This commit fixes the missing spinlock init for the
waiting_sks list. We also eliminate the race condition
between the waiting_sks length check/dequeue operations in
tipc_bclink_wakeup_users by simply removing the redundant
length check.

Redefine REALTEK_USB_DEVICE for the desired USB interface for probe().
There are three USB interfaces for the device. USB_CLASS_COMM and
USB_CLASS_CDC_DATA are for ECM mode (config #2). USB_CLASS_VENDOR_SPEC
is for the vendor mode (config #1). However, we are not interesting
in USB_CLASS_CDC_DATA for probe(), so redefine REALTEK_USB_DEVICE
to ignore the USB interface class of USB_CLASS_CDC_DATA.

Commit ce1a4ea3f125 ("net: avoid one atomic operation in skb_clone()")
took the wrong way to save one atomic operation.
It is actually possible to avoid two atomic operations, if we
do not change skb->fclone values, and only rely on clone_ref
content to signal if the clone is available or not.
skb_clone() can simply use the fast clone if clone_ref is 1.
kfree_skbmem() can avoid the atomic_dec_and_test() if clone_ref is 1.
Note that because we usually free the clone before the original skb,
this particular attempt is only done for the original skb to have better
branch prediction.
SKB_FCLONE_FREE is removed.

The commit 56bfa7ee7c ("unregister_netdevice : move RTM_DELLINK to
until after ndo_uninit") tried to do this ealier but while doing so
it created a problem. Unfortunately the delayed rtmsg_ifinfo() also
delayed call to fill_info(). So this translated into asking driver
to remove private state and then query it's private state. This
could have catastropic consequences.
This change breaks the rtmsg_ifinfo() into two parts - one takes the
precise snapshot of the device by called fill_info() before calling
the ndo_uninit() and the second part sends the notification using
collected snapshot.
It was brought to notice when last link is deleted from an ipvlan device
when it has free-ed the port and the subsequent .fill_info() call is
trying to get the info from the port.

To accomodate for enough headroom for tunnels, use MAX_HEADER instead
of LL_MAX_HEADER. Robert reported that he has hit after roughly 40hrs
of trinity an skb_under_panic() via SCTP output path (see reference).
I couldn't reproduce it from here, but not using MAX_HEADER as elsewhere
in other protocols might be one possible cause for this.
In any case, it looks like accounting on chunks themself seems to look
good as the skb already passed the SCTP output path and did not hit
any skb_over_panic(). Given tunneling was enabled in his .config, the
headroom would have been expanded by MAX_HEADER in this case.

In recent testing I had disabled CONFIG_IP_MULTIPLE_TABLES and as a result
when I ran "cat /proc/net/fib_trie" the main trie was displayed multiple
times. I found that the problem line of code was in the function
fib_trie_seq_next. Specifically the line below caused the indexes to go in
the opposite direction of our traversal:
h = tb->tb_id & (FIB_TABLE_HASHSZ - 1);
This issue was that the RT tables are defined such that RT_TABLE_LOCAL is ID
255, while it is located at TABLE_LOCAL_INDEX of 0, and RT_TABLE_MAIN is 254
with a TABLE_MAIN_INDEX of 1. This means that the above line will return 1
for the local table and 0 for main. The result is that fib_trie_seq_next
will return NULL at the end of the local table, fib_trie_seq_start will
return the start of the main table, and then fib_trie_seq_next will loop on
main forever as h will always return 0.
The fix for this is to reverse the ordering of the two tables. It has the
advantage of making it so that the tables now print in the same order
regardless of if multiple tables are enabled or not. In order to make the
definition consistent with the multiple tables case I simply masked the to
RT_TABLE_XXX values by (FIB_TABLE_HASHSZ - 1). This way the two table
layouts should always stay consistent.

This patch extends the set/get_rxfh ethtool-options for getting or
setting the RSS hash function.
It modifies drivers implementation of set/get_rxfh accordingly.
This change also delegates the responsibility of checking whether a
modification to a certain RX flow hash parameter is supported to the
driver implementation of set_rxfh.
User-kernel API is done through the new hfunc bitmask field in the
ethtool_rxfh struct. A bit set in the hfunc field is corresponding to an
index in the new string-set ETH_SS_RSS_HASH_FUNCS.
Got approval from most of the relevant driver maintainers that their
driver is using Toeplitz, and for the few that didn't answered, also
assumed it is Toeplitz.

mvneta_tx() dereferences skb to get skb->len too late,
as hardware might have completed the transmit and TX completion
could have freed the skb from another cpu.
Fixes: 71f6d1b31fb1 ("net: mvneta: replace Tx timer with a real interrupt")

since head->handle == handle (checked before), just assign handle.

rcu variant is not correct here. The code is called by updater (rtnl
lock is held), not by reader (no rcu_read_lock is held).
