> This patch adds bpf_xdp_adjust_head() support to mlx5e. > > 1. rx_headroom is added to struct mlx5e_rq. It uses > an existing 4 byte hole in the struct. > 2. The adjusted data length is checked against > MLX5E_XDP_MIN_INLINE and MLX5E_SW2HW_MTU(rq->netdev->mtu). > 3. The macro MLX5E_SW2HW_MTU is moved from en_main.c to en.h. > MLX5E_HW2SW_MTU is also moved to en.h for symmetric reason > but it is not a must. > > v2: > - Keep the xdp specific logic in mlx5e_xdp_handle() > - Update dma_len after the sanity checks in mlx5e_xmit_xdp_frame() > > Signed-off-by: Martin KaFai Lau <ka...@fb.com> Applied.
