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 <kafai@fb.com> Acked-by: Saeed Mahameed <saeedm@mellanox.com> Signed-off-by: David S.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
