Currently there is a race between incoming traffic and
initialization flow. HW is able to receive the packets
after INIT_PORT is done and unicast steering is configured.
Before we set priv->port_up NAPI is not scheduled and
receive queues become full. Therefore we never get
new interrupts about the completions.
This issue could happen if running heavy traffic during
bringing port up.
The resolution is to schedule NAPI once port_up is set.
If receive queues were full this will process all cqes
and release them.

The resource type enum in the resource tracker was incorrect.
RES_EQ was put in the position of RES_NPORT_ID (a FC resource).
Since the remaining resources maintain their current values,
and RES_EQ is not passed from slaves to the hypervisor in any
FW command, this change affects only the hypervisor.
Therefore, there is no backwards-compatibility issue.

====================
40GbE Intel Wired LAN Driver Updates 2016-10-28
This series contains updates to i40e and i40evf only.
Carolyn provides a couple of fixes, first resolving a problem in the
client interface that was causing random stack traces in the RDMA driver
which was due to a timing related NULL pointer dereference. Fixed a
problem where it could take a very long time to print the link down
notification, by changing how often we update link info from firmware.
Alex provides a number of changes, first is a re-write of the bust wait
loop in the Flow Director transmit function to reduce code size. Cleans
up unused code in favor of the same functionality which can be inlined.
Dropped the functionality for SCTP since we cannot currently support it.
Cleans up redundant code in the receive clean-up path. Finally cleaned
up the convoluted configuration for how the driver handled the debug
flags contained in msg_level.
Filip fixes an incorrect bit mask which was being used for testing the
"get link status". Cleaned up a workaround that is no longer needed
for production NICs and was causing frames to pass while disregarding
the VLAN tagging.
Mitch brings another fix for the client interface supporting the VF RDMA
driver to allow clients to recover from reset by re-opening existing
clients.
Alan fixes a bug in which a "perfect storm" can occur and cause interrupts
to fail to be correctly affinitized.
Lihong fixes a confusing dmesg reported when users were using ethtool -L
option.

So the i40e driver had a really convoluted configuration for how to handle
the debug flags contained in msg_level. Part of the issue is that the
driver has its own 32 bit mask that it was using to track a separate set of
debug features. From what I can tell it was trying to use the upper 4 bits
to determine if the value was meant to represent a bit-mask or the numeric
value provided by debug level.
What this patch does is clean this up by compressing those 4 bits into bit
31, as a result we just have to perform a check against the value being
negative to determine if we are looking at a debug level (positive), or a
debug mask (negative). The debug level will populate the msg_level, and
the debug mask will populate the debug_mask in the hardware struct.
I added similar logic for ethtool. If the value being provided has bit 31
set we assume the value being provided is a debug mask, otherwise we assume
it is a msg_enable mask. For displaying we only provide the msg_enable,
and if debug_mask is in use we will print it to the dmesg log.
Lastly I removed the debugfs interface. It is redundant with what we
already have in ethtool and really doesn't belong anyway.

Patch a036244c0686 "i40e: Fix kernel panic on enable/disable LLDP"
introduced an error in bit logic.
Originally this bit manipulation was meant to clear two bits to indicate
that DCB was not enabled or capable. An "&" was incorrectly used instead
of an "|" bit operator to combine the two bitmasks into one. This also
created a static checker error since the resultant code was a no-op.
This patch fixes the error by using the correct bit-wise operator.

This is code refactoring. This patch removes the workaround which deleted
a default MAC filter added by the firmware when the interface was brought

It used to be automatically applied after reset in pre-SRA FW versions.
This workaround is not needed in production NICs and hence can be removed.

This patch cleans up several pieces of redundant code in the Rx clean-up
paths.
The first bit is that hdr_addr and the status_err_len portions of the Rx
descriptor represent the same value. As such there is no point in setting
them to 0 before setting them to 0. I'm dropping the second spot where we
are updating the value to 0 so that we only have 1 write for this value
instead of 2.
The second piece is the checking for the DD bit in the packet. We only
need to check for a non-zero value for the status_err_len because if the
device is done with the descriptor it will have written something back and
the DD is just one piece of it. In addition I have moved the reading of
the Rx descriptor bits related to rx_ptype down so that they are actually
below the dma_rmb() call so that we are guaranteed that we don't have any
funky 64b on 32b calls causing any ordering issues.

Ethtool -L option with the combined parameter is for changing the number of
multi-purpose channels of the specified network device. The pre-set maximum
for the combined channels is cpu dependent. Currently, for an i40e device,
when the user sets a value between 64 and the maximum that the cpu can
support for the combined parameter, the i40e driver displays the confusing
info in dmesg to only show 64 as the RSS count regardless of what the
accepted user input is as long as it is larger than 64.
This patch fixes the message in the i40e driver when the user uses
ethtool -L to change the number of the combined channels to consistently
display the user requested value if it is valid and accepted by ethtool.

There exists a bug in which a 'perfect storm' can occur and cause
interrupts to fail to be correctly affinitized. This causes unexpected
behavior and has a substantial impact on performance when it happens.
The bug occurs if there is heavy traffic, any number of CPUs that have
an i40e interrupt are pegged at 100%, and the interrupt afffinity for
those CPUs is changed. Instead of moving to the new CPU, the interrupt
continues to be polled while there is heavy traffic.
The bug is most readily realized as the driver is first brought up and
all interrupts start on CPU0. If there is heavy traffic and the
interrupt starts polling before the interrupt is affinitized, the
interrupt will be stuck on CPU0 until traffic stops. The bug, however,
can also be wrought out more simply by affinitizing all the interrupts
to a single CPU and then attempting to move any of those interrupts off
while there is heavy traffic.
This patch fixes the bug by registering for update notifications from
the kernel when the interrupt affinity changes. When that fires, we
cache the intended affinity mask. Then, while polling, if the cpu is
pegged at 100% and we failed to clean the rings, we check to make sure
we have the correct affinity and stop polling if we're firing on the
wrong CPU. When the kernel successfully moves the interrupt, it will
start polling on the correct CPU. The performance impact is minimal
since the only time this section gets executed is when performance is
already compromised by the CPU.

Allow the client interface to reopen existing clients if they were
closed. This allows clients to recover from reset, which is essential
for supporting VF RDMA. In one instance, the driver was not clearing the
open bit when the client was closed. Add the code to clear this bit so
that the state is accurate and the driver will not attempt to reopen
already-open clients. Remove the ref_cnt variable; it was just getting

So far, mlxsw_pci.ko is the module that registers PCI table for all
drivers (spectrum and switchx2). That is problematic for example with
dracut. Since mlxsw_spectrum.ko and mlxsw_switchx2.ko are loaded
dynamically from within mlxsw_core.ko, dracut does not have track of
them and avoids them from being included in initramfs.
So make this in an ordinary way and define the PCI tables in individual
driver modules, so it can be properly loaded and included in dracut
initramfs image. As a side effect, this patch could remove no longer
necessary driver "kind" strings which were used to link PCI ids with
individual mlxsw drivers.
