This series contains updates to i40e, ixgbe, and ice drivers.

Magnus Karlsson says:

Optimize run_xdp_zc() for the XDP program verdict being XDP_REDIRECT
in the xsk zero-copy path. This path is only used when having AF_XDP
zero-copy on and in that case most packets will be directed to user
space. This provides around 100k extra packets in throughput on my
server when running l2fwd in xdpsock.

The following are changes since commit 2117fce81f6b862aac0673abe8df0c60dca64bfa:
  Merge branch 'psample-Add-additional-metadata-attributes'
and are available in the git repository at:
  git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue 40GbE

Magnus Karlsson (3):
  i40e: optimize for XDP_REDIRECT in xsk path
  ixgbe: optimize for XDP_REDIRECT in xsk path
  ice: optimize for XDP_REDIRECT in xsk path

Looks reasonable:
