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 drivers/net/ethernet/intel/i40e/i40e_main.c | 3 - drivers/net/ethernet/intel/i40e/i40e_txrx.c | 91 ++++++------------- drivers/net/ethernet/intel/i40e/i40e_txrx.h | 1 + drivers/net/ethernet/intel/i40e/i40e_xsk.c | 4 +- drivers/net/ethernet/intel/ice/ice_main.c | 9 -- drivers/net/ethernet/intel/ice/ice_txrx.c | 88 ++++++++---------- drivers/net/ethernet/intel/ice/ice_txrx.h | 3 +- drivers/net/ethernet/intel/ice/ice_xsk.c | 7 +- drivers/net/ethernet/intel/ixgbe/ixgbe.h | 1 + drivers/net/ethernet/intel/ixgbe/ixgbe_main.c | 15 +-- 10 files changed, 86 insertions(+), 136 deletions(-) -- 2.20.1
