During resets (possibly caused by a Tx hang) the driver would
accidentally clear the XPS mask for all queues back to 0.
This caused higher CPU utilization and had some other performance impacts
for transmit tests.

Intel Wired LAN Driver Updates 2015-03-03
This series contains updates to fm10k, i40e and i40evf.
Matthew updates the fm10k driver by cleaning up code comments and whitespace
issues. Also modifies the tunnel length header check, to make it more robust
by calculating the inner L4 header length based on whether it is TCP or UDP.
Implemented ndo_features_check() that allows drivers to report their offload
capabilities per-skb.
Neerav updates the i40e driver to skip over priority tagging if DCB is not
enabled. Fixes an issue where the driver is not flushing out the
DCBNL app table for applications that are not present in the local DCBX
application configuration TLVs. Fixed i40e where, in the case of MFP
mode, the driver was returning the incorrect number of traffic classes
for partitions that are not enabled for iSCSI. Even though the driver
was not configuring these traffic classes in the transmit scheduler for
the NIC partitions, it does use this map to setup the queue mappings.
Shannon updates i40e/i40evf to include the firmware build number in the
formatted firmware version string.
Akeem adds a safety net (by adding a 'default' case) for the possible
unmatched switch calls.
Mitch updates i40e to not automatically disable PF loopback at runtime,
now that we have the functionality to enable and disable PF loopback. This
fix cleans up a bogus error message when removing the PF module with VFs
enabled. Adds a extra check to make sure that the indirection table
pointer is valid before dereferencing it.
Anjali enables i40e to enable more than the max RSS qps when running in a
single TC mode for the main VSI. It is possible to enable as many as
num_online_cpus(). Adds a firmware check to ensure that DCB is disabled for
firmware versions older than 4.33. Updates i40e/i40evf to add missing
packet types for VXLAN offload. Updated i40e to be able to handle varying
RSS table size for each VSI, since all VSI's do not have the same RSS table
size.
v2: Dropped previous patch #9 "i40e/i40evf: Add capability to gather VEB
per TC stats" since the stats should be in ethtool and not debugfs.

With changes to default number of queue pairs that the interface comes up with
from 1 per online CPU to 1 per lan_msix, we need to make sure we recalculate
rss_size. We will now recalculate rss_size based on number of queues enabled in
the VSI.
Without this fix if the max_lan_msix < num_online_cpu we will be coming up
with fewer queues but will be populating rss_size based on num_online_cpus.
This will result in packets getting silently dropped because RSS LUT has queues
that are not enabled.

Add support for bridge offload ndo_ops getlink and setlink to
enable bridge hardware mode as per the mode set via IFLA_BRIDGE_MODE.
The support is only enabled in case of a PF VSI and not available for
any other VSI type.
By default the i40e driver inserts a bridge as part of the bring-up
when a FDIR type VSI and/or a FCoE VSI is created. This bridge is
created in VEB mode by default i.e. after creating the bridge using
"Add VEB" AQ command the loopback for the PF's default VSI is enabled.
The patch adds capability where all the VSIs created as downlink to
the bridge inherits the loopback property and enables loopback only
if the uplink bridge is operating in VEB mode.
Hence, there is no need to explicitly enable loopback as part of
allocating resources for SR-IOV VFs and call to do that has been
removed.
In case a user-request is made either via "bridge" utility or using
the bridge netlink interface that requires to change the hardware
bridge mode then that would require a PF reset and rebuild of the
switch hierarchy.
