This series contains updates to i40e driver only.

Li RongQing removes binding affinity mask to a fixed CPU and sets
prefetch of Rx buffer page to occur conditionally.

Björn provides AF_XDP performance improvements by not prefetching HW
descriptors, using 16 byte descriptors, and moving buffer allocation
out of Rx processing loop.

v2: Define prefetch_page_address in a common header for patch 2.
Dropped, previous, patch 5 as it is being reworked to be more
generalized.

The following are changes since commit e059c6f340f6fccadd3db9993f06d4cc51305804:
  tulip: switch from 'pci_' to 'dma_' API
and are available in the git repository at:
  git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue 40GbE

Björn Töpel (3):
  i40e, xsk: remove HW descriptor prefetch in AF_XDP path
  i40e: use 16B HW descriptors instead of 32B
  i40e, xsk: move buffer allocation out of the Rx processing loop

Li RongQing (2):
  i40e: not compute affinity_mask for IRQ
  i40e: optimise prefetch page refcount

Looks good, pulled, thanks Tony.
