Merge branch '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue 

Jeff Kirsher says:

====================
40GbE Intel Wired LAN Driver Updates 2016-02-17

This series contains updates to i40e/i40evf only (again).

Jesse moves sync_vsi_filters() up in the service_task because it may need
to request a reset, and we do not want to wait another round of service
task time.  Refactored the enable_icr0() in order to allow it to be
decided by the caller whether the CLEARPBA (clear pending events) bit will
be set while re-enabling the interrupt.  Also provides the "Don't Give Up"
patch, where the driver will keep polling trying to allocate receive buffers
until it succeeds.  This should keep all receive queues running even in
the face of memory pressure.  Cleans up the debugging helpers by putting
everything in hex to be consistent.

Neerav updates the DCB firmware version related checkes specific to X710
and XL710 only since the checks are not required for X722 devices.

Shannon adds the use of the new shared MAC filter bit for multicast and
broadcast filters in order to make better use of the filters available
from the device.  Added a parameter to allow the driver to set the
enable/disable of statistics gathering in the hardware switch.  Also the
L2 cloud filtering parameter is removed since it was never used.

Anjali refactors the force_wb and WB_ON_ITR functionality since
Force-WriteBack functionality in X710/XL710 devices has been moved out of
the clean routine and into the service task, so we need to make sure
WriteBack-On-ITR is separated out since it is still called from clean.

Catherine changes the VF driver string to reflect all the products that
are supported.

Mitch refactors the packet split receive code to properly use half-pages
for receives.  Also changes the use of bitwise operators to logical
operators on clean_complete variable, while making a witty reference to
Mr. Spock.  Cleans up (i.e. removes) the hsplit field in the ring
structure and use the existing macro to detect packet split enablement,
which allows debugfs dumps of the VSI to properly show which recevie
routine is in use.
