Subject: [PATCH v3 net-next 00/11] intel driver cleanups

Hi,

This series is mostly about the cleanups on Rx (ZC/normal) paths both in
ice and i40e drivers. Things that stand out are the simplifactions of
ice_change_mtu and i40e_xdp_setup.

Third iteration of this includes patches that optimize the handling of
*_rx_offset() calls per each processed frame. Some cycles can be saved
by storing the result of that function onto rx ring. For that, I am
using existing holes within ring structs (checked with pahole).

Thanks!

v3: rebase, fix handling rx offset
v2: fix kdoc in patch 5 (Jakub)
