The initial patches do some code refactoring, preparing the code base to land the AF_XDP zero-copy feature, avoiding code duplications. The last patches of the series are the ones implementing the feature. The last patch which indeed implements AF_XDP zero-copy support was originally way too lengthy so, for the sake of code review, I broke it up into two patches: one adding support for the RX functionality and the other one adding TX support. Feel free to squash those two patches when pushing the series to net-next if you find appropriate. Best, Andre Andre Guedes (10): igc: Move igc_xdp_is_enabled() igc: Refactor igc_xdp_run_prog() igc: Refactor igc_clean_rx_ring() igc: Refactor XDP rxq info registration igc: Introduce igc_update_rx_stats() igc: Introduce igc_update_tx_stats() igc: Introduce igc_unmap_tx_buffer() helper igc: Replace IGC_TX_FLAGS_XDP flag by an enum igc: Enable RX via AF_XDP zero-copy igc: Enable TX via AF_XDP zero-copy drivers/net/ethernet/intel/igc/igc.h | 33 +- drivers/net/ethernet/intel/igc/igc_base.h | 2 + drivers/net/ethernet/intel/igc/igc_main.c | 650 ++++++++++++++++++---- drivers/net/ethernet/intel/igc/igc_xdp.c | 107 +++- drivers/net/ethernet/intel/igc/igc_xdp.h | 8 +- 5 files changed, 672 insertions(+), 128 deletions(-) -- 2.29.2
