This series contains four patches worth of driver tweaks for the i40e AF_XDP Rx path, that in total improves the Rx performance (rx_drop 64B packets-per-second) with 17%. Please refer to the individual commits for more details. Cheers, Björn Björn Töpel (4): i40e, xsk: remove HW descriptor prefetch in AF_XDP path i40e: use 16B HW descriptors instead of 32B i40e, xsk: increase budget for AF_XDP path i40e, xsk: move buffer allocation out of the Rx processing loop drivers/net/ethernet/intel/i40e/i40e.h | 2 +- .../net/ethernet/intel/i40e/i40e_debugfs.c | 10 +++---- drivers/net/ethernet/intel/i40e/i40e_main.c | 4 +-- drivers/net/ethernet/intel/i40e/i40e_trace.h | 6 ++-- drivers/net/ethernet/intel/i40e/i40e_txrx.c | 19 +++++++++++-- drivers/net/ethernet/intel/i40e/i40e_txrx.h | 2 +- .../ethernet/intel/i40e/i40e_txrx_common.h | 13 --------- drivers/net/ethernet/intel/i40e/i40e_type.h | 5 +++- drivers/net/ethernet/intel/i40e/i40e_xsk.c | 28 +++++++++++++------ 9 files changed, 50 insertions(+), 39 deletions(-) base-commit: 23212a70077311396cda2823d627317c25e6e5d1 -- 2.25.1
