Convert mvneta, mvpp2 and mlx5 drivers to xdp_return_frame_bulk APIs. Changes since v2: - move mvneta changes in a dedicated patch Changes since v1: - improve comments - rework xdp_return_frame_bulk routine logic - move count and xa fields at the beginning of xdp_frame_bulk struct - invert logic in page_pool_put_page_bulk for loop Lorenzo Bianconi (5): net: xdp: introduce bulking for xdp tx return path net: page_pool: add bulk support for ptr_ring net: mvneta: add xdp tx return bulking support net: mvpp2: add xdp tx return bulking support net: mlx5: add xdp tx return bulking support drivers/net/ethernet/marvell/mvneta.c | 5 +- .../net/ethernet/marvell/mvpp2/mvpp2_main.c | 5 +- .../net/ethernet/mellanox/mlx5/core/en/xdp.c | 5 +- include/net/page_pool.h | 26 +++++++++ include/net/xdp.h | 9 +++ net/core/page_pool.c | 35 ++++++++++++ net/core/xdp.c | 56 +++++++++++++++++++ 7 files changed, 138 insertions(+), 3 deletions(-)
