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 2017-03-15

This series contains updates to i40e and i40evf only.

Aaron fixes an issue on x710 devices where simultaneous read accesses
were interfering with each other, so make sure all devices acquire the
NVM lock before reads on all devices.

Shannon adds Wake On LAN support feature for x722 devices and cleaned
up the opcodes so that they are in numerical order.

Mitch adds a client interface to the VF driver, in preparation for the
upcoming RDMA-capable hardware (and client driver).  Cleaned up the
client interface in the PF driver, since it was originally over
engineered to handle multiple clients on multiple netdevs, but that
did not happen and now there will be one client per driver, so apply
the "KISS" (Keep It Simple & Stupid) to the i40e client interface.
Bumped the number of MAC filters an untrusted VF can create.

Jake fixes an issue where a recent refactor of queue pairs accidentally
added all remaining vecotrs to the num_lan_msix which can adversely
affect performance.

Lihong fixes an ethtool issue with x722 devices where "-e" will error
out since its EEPROM has a scope limit at offset 0x5B9FFF, so set the
EEPROM length to the scope limit.  Also fixed an issue where RSS
offloading only worked on PF0.

Filip cleans up and clarifies code comment so there is no confusion
about MAC/VLAN filter initialization routine.

Alex adds support for DMA_ATTR_SKIP_CPU_SYNC and DMA_ATTR_WEAK_ORDERING,
which improves performance on architectures that implement either one.

Harshitha cleans up confusion on flags disabled due to hardware limitation
versus featured disabled by the user, so rename auto_disable_flags to
hw_disabled_flags to avoid the confusion.

v2: Merged patch #1 and #4 in first version to make patch #3 in this
    series based on feedback from David Miller.
