In SRIOV, when simple (i.e - Ethernet L2 only) flow steering rules are
created, always create them at MLX4_DOMAIN_NIC priority (instead of
the real priority the function created them at). This is done in order
to let multiple functions add broadcast/multicast rules without
affecting other functions, which is necessary for DPDK in SRIOV.

This is the Ethernet part of the driver for the Mellanox ConnectX(R)-4
Single/Dual-Port Adapter supporting 100Gb/s with VPI. The driver
extends the existing mlx5 driver with Ethernet functionality.
This patch contains the driver entry points but does not include
transmit and receive (see the previous patch in the series) routines.
It also adds the option MLX5_CORE_EN to Kconfig to enable/disable the
Ethernet functionality. Currently, Kconfig is programmed to make
Ethernet and Infiniband functionality mutally exclusive.
Also changed MLX5_INFINIBAND to be depandant on MLX5_CORE instead of
selecting it, since MLX5_CORE could be selected without MLX5_INFINIBAND
being selected.

This patch contains the resource handling files:
- flow_table.c: This file contains the code to handle the low level API
to configure hardware flow table. It is separated from
the flow_table_en.c, because it will be used in the
future by Raw Ethernet QP in mlx5_ib too.
- en_flow_table.[ch]: Ethernet flow steering handling. The flow table
object contain a mapping between flow specs and TIRs.
This mechanism will be used also to configure e-switch
in the future, when SR-IOV support will be added.
- transobj.[ch] - Low level functions to create/modify/destroy the
transport objects: RQ/SQ/TIR/TIS
- vport.[ch] - Handle attributes of a virtual port (vPort) in the
embedded switch. Currently this switch is a passthrough, until SR-IOV
support will be added.

en_[rt]x.c contains the data path related code specific to tx or rx.
en_txrx.c contains data path code which is common for both the rx and
tx, this is mainly napi related code.
Below are the objects that are being used by the hardware and the driver
in the data path:
Channel - one channel per IRQ. Every channel object contains:
RQ - describes the rx queue
TIR - One TIR (Transport Interface Receive) object per flow type. TIR
contains attributes for a type of rx flow (e.g IPv4, IPv6 etc).
A flow is defined in the Flow Table.
Currently TIR describes the RSS hash parameters if exists and LRO
attributes.
SQ - describes the a tx queue. There is one SQ (Send Queue) per
TC (traffic class).
TIS - There is one TIS (Transport Interface Send) per TC. It
describes the TC and may later be extended to describe more
transport properties.
Both RQ and SQ inherit from the object WQ (work queue). This common code
to describe the layout of CQE's WQE's in memory is in the files wq.[cj]
For every channel there is one NAPI context that is used for RX and
for TX.
Driver is using netdev_alloc_skb() to allocate skb's.

As David Daney pointed in mlx4_core driver [1], mlx5_core is also
misusing the DMA-API.
This patch is removing the code that vmap() memory allocated by
dma_alloc_coherent().
After this patch, users of this drivers might fail allocating resources
on memory fragmeneted systems. This will be fixed later on.

Jeff Kirsher says:
====================
Intel Wired LAN Driver Updates 2015-05-28
This series contains updates to ethtool, ixgbe, i40e and i40evf.
John adds helper routines for ethtool to pass VF to rx_flow_spec. Since
the ring_cookie is 64 bits wide which is much larger than what could be
used for actual queue index values, provide helper routines to pack a VF
index into the cookie. Then John provides a ixgbe patch to allow flow
director to use the entire queue space.
Neerav provides a i40e patch to collect XOFF Rx stats, where it was not
being collected before.
Anjali provides ATR support for tunneled packets, as well as stats to
count tunnel ATR hits. Cleaned up PF struct members which are
unnecessary, since we can use the stat index macro directly. Cleaned
up flow director ATR/SB messages to a higher debug level since they
are not useful unless silicon validation is happening.
Greg provides a patch to disable offline diagnostics if VFs are enabled
since ethtool offline diagnostic tests are not designed (out of scope)
to disable VF functions for testing and re-enable afterward. Also cleans
up TODO comment that is no longer needed.
Vasu provides a fix an FCoE EOF case where i40e_fcoe_ctxt_eof() maybe
called before i40e_fcoe_eof_is_supported() is called.
Jesse adds skb->xmit_more support for i40evf. Then provides a performance
enhancement for i40evf by inlining some functions which provides a 15%
gain in small packet performance. Also cleans up the use of time_stamp
since it is no longer used to determine if there is a tx_hang and was
a part of a previous tx_hang design which is no longer used.

The current algorithm for deciding on the number of VRSS channels is
not optimal since we open up the min of number of CPUs online and the
number of VRSS channels the host is offering. So on a 32 VCPU guest
we could potentially open 32 VRSS subchannels. Experimentation has
shown that it is best to limit the number of VRSS channels to the number
of CPUs within a NUMA node.
Here is the new algorithm for deciding on the number of sub-channels we
would open up:
1) Pick the minimum of what the host is offering and what the driver
in the guest is specifying as the default value.
2) Pick the minimum of (1) and the numbers of CPUs in the NUMA
node the primary channel is bound to.

In some cases some channel survey data was
reported incorrect.
Channel info events were expected to come in pairs
without and with COMPLETE flag set respectively
for each channel visit during scan.
The known deviation from this is rule for last
scan chan info and first (next) scan chan info
both have COMPLETE flag set. This was either
programmed with the intent of providing BSS cycle
count info or this is an artefact of firmware scan
state machine. Either way this is useless due to
short wraparound time, wraparound quirks and no
overflow notification.
Survey dumps now include only data gathered during
scan channel visits that can be computed
correctly.
This should improve hostapd ACS a little bit.

When QCA988X cycle counter HW register wraps
around it resets to 0x7fffffff instead of 0. All
other cycle counter related registers are divided
by 2 so they never wraparound themselves. QCA61X4
has a uniform CC and it wraparounds in a regular
fashion though.
Worst case wraparound time is approx 24 seconds
(2**31 / 88MHz). Since scan channel visit times
are max 5 seconds (offchannel case) it is
guaranteed there's been at most 1 wraparound and
it is possible to compute survey active time
value. It is, however, impossible to determine the
point at which Rx Clear Count has been divided by
two so it is not reported upon wraparound.
This fixes some occasional incorrect survey data
on QCA988X as some channels (depending on how/when
scan/offchannel requests were requested) would
have approx 24 sec active time which wasn't
actually the case.
This should improve hostapd ACS a little bit.

Replace confusing QL_STATUS_INVALID_PARAM == -1 == -EPERM with -EINVAL

so let it be here as well.

Because i40e_fcoe_ctxt_eof should never be called without
i40e_fcoe_eof_is_supported being called first, the EOF in fcoe_ctxt_eof
should always be valid and therefore we do not need to print an error
if it is not valid.
However, a WARN ON to easily catch any calls to i40e_fcoe_ctxt_eof that
aren't preceded with a call to i40e_fcoe_eof_is_supported is helpful.

queues with the right core/interrupt.

BlockAck sessions can have events that are interesting to
debug. When we send or receive a BAR, it is may indicate
that something bad is happening. Even more so when mac80211
tells us that a frame timed out in the reodering buffer.
Add a few triggers for BlockAck session debugging.
Allow per-TID debugging.

Lots of updates for net-next for this cycle. As usual, we have
a lot of small fixes and cleanups, the bigger items are:
* proper mac80211 rate control locking, to fix some random crashes
(this required changing other locking as well)
* mac80211 "fast-xmit", a mechanism to reduce, in most cases, the
amount of code we execute while going from ndo_start_xmit() to
the driver
* this also clears the way for properly supporting S/G and checksum
and segmentation offloads

Require the user to disable virtual functions before running the device
offline diagnostics. The offline diagnostics are intended to ensure
basic operation of the device - it is beyond the scope of the diagnostic
test to handle the additional complexity of bringing all the virtual
functions offline and then back online for each test run.

When PFC is enabled for any UP in single TC configuration the driver didn't
collect the PFC XOFF RX stats. Though a single TC with PFC enabled is not a
common scenario do not prevent the driver from collecting stats if firmware
indicates that PFC is enabled.

For UMAC, we were not treating a race condition that happens in the
scan flows, because it was not using the same state flags. Now that
UMAC and LMAC scans use the same state flags, we can also handle the
race conditions for UMAC.

UMAC scans now use the general scan status for almost everything, the
only part missing was in the scan complete notifications. Change it
to use the stopping flags instead of clearing the flags when the stop
comes from above and clean the handler function a bit.

We can only have one scan per type at the same time, so the code that
tries to stop several scans of a type is unnecessary. Remove that to

We can only have one scan of each type running at the same time, so we
can remove one attribute in the UID information we save. We had array
index, UID and type, but only UID (== array_index) and type are
necessary. Refactor the code to use this simplified array.

Add support for scan priority API with 8 levels instead of the
existing 3 levels. This API is needed to define the priority of
new ooc activities, e.g. gscan.
Add a TLV flag to indicate if the new API is supported so that
devices that does not support the new API will continue to use
the old one.
