Subject: [PATCH v3 net-next 00/11] intel driver cleanups
Date: Mon, 18 Jan 2021 16:13:07 +0100	[thread overview]
Message-ID: <20210118151318.12324-1-maciej.fijalkowski@intel.com> (raw)

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)


Björn Töpel (1):
  i40e, xsk: Simplify the do-while allocation loop

Maciej Fijalkowski (10):
  i40e: drop redundant check when setting xdp prog
  i40e: drop misleading function comments
  i40e: adjust i40e_is_non_eop
  ice: simplify ice_run_xdp
  ice: move skb pointer from rx_buf to rx_ring
  ice: remove redundant checks in ice_change_mtu
  ice: skip NULL check against XDP prog in ZC path
  i40e: store the result of i40e_rx_offset() onto i40e_ring
  ice: store the result of ice_rx_offset() onto ice_ring
  ixgbe: store the result of ixgbe_rx_offset() onto ixgbe_ring
