Merge branch 'mlx5e-xdp'
Tariq Toukan says: ==================== mlx5e XDP support This series adds XDP support in mlx5e driver. This includes the use cases: XDP_DROP, XDP_PASS, and XDP_TX. Single stream performance tests show 16.5 Mpps for XDP_DROP, and 12.4 Mpps for XDP_TX, with nice scalability for multiple streams/rings. This rate of XDP_DROP is lower than the 32 Mpps we got in previous implementation, when Striding RQ was used. We moved to non-Striding RQ, as some XDP_TX requirements (like headroom, packet-per-page) cannot be satisfied with the current Striding RQ HW, and we decided to fully support both DROP/TX. Few directions are considered in order to enable the faster rate for XDP_DROP, e.g a possibility for users to enable Striding RQ so they choose optimized XDP_DROP on the price of partial XDP_TX functionality, or some HW changes. Series generated against net-next commit: cf714ac1 'ipvlan: Fix dependency issue' Thanks, Tariq V2: * patch 8: - when XDP_TX fails, call mlx5e_page_release and drop the packet. - update xdp_tx counter within mlx5e_xmit_xdp_frame. (mlx5e_xmit_xdp_frame return value becomes obsolete, change it to void) - drop the packet for unknown XDP return code. * patch 9: - use a boolean for xdp_doorbell in SQ struct, instead of dragging it throughout the functions calls. - handle doorbell and counters within mlx5e_xmit_xdp_frame. ==================== Signed-off-by: David S.
