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.

Jesse cleans up a duplicate declaration in probe.  Then fixes a bug where the
driver was using a offset based off a DMA handle while mapping and unmapping
using sync_single_range_for_[cpu|device], when it should be using DMA handle
(returned from alloc_coherent) and the offset of the memory to be sync'd.
Fixed an issue where sync_vsi_filter() was allocating memory in a way that
could sleep (GFP_KERNEL) which was causing a problem when called by the
team driver under rcu_read_lock().

Shannon adds a check to ensure we do not attempt to do TSO when
skb->ip_summed is not set to CHECKSUM_PARTIAL.

Kiran add functions related to port mirroring features such as add/delete
mirror rule.

Jacob assigns the i40e_pf structure directly instead of using a large
memcpy, to avoid a sparse warning and lets the compiler optimize the copy
since it know the size of the structure in advance.

Anjali enables GENEVE capability for XL710/X710 devices with firmware API
version higher than 1.4.  Added flag for automatic rule eviction feature
for X722, which is disabled by default.
