Notes on the feedback from net-next v1 posting [0]: - It correctly complains about ABI breakage for 32 bit systems, added an explanation why I think we unlikely to have any 32 bit users with launch time - mlx5 batching (pre existing) - I think my point in the comment still stays (that we do not make it worse) - stmmac recycled descriptors (pre existing) - seems valid but I don't feel confident sending a vibe-coded fix - stmmac queueMaxSDU vs taprio offload - don't think this is real but we can fix separately later if it is (the existing issue with breaking xsk seems more real) v2: - target net, address clashiko feedback (mostly here and other commit descriptions) 0: from https://netdev-ai.bots.linux.dev/sashiko/#/message/20260810184753.135756-1-sdf%40fomichev.me Stanislav Fomichev (3): xsk: align TX metadata layout across ABIs xsk: honor XDP_TX_METADATA in zero-copy path net: stmmac: skip queueMaxSDU check for AF_XDP drivers/net/ethernet/intel/igc/igc_main.c | 3 ++- .../ethernet/mellanox/mlx5/core/en/xsk/tx.c | 2 +- .../net/ethernet/stmicro/stmmac/stmmac_main.c | 10 ++------- include/net/libeth/xsk.h | 2 +- include/net/xdp_sock_drv.h | 22 +++++++++++-------- include/net/xsk_buff_pool.h | 3 ++- include/uapi/linux/if_xdp.h | 1 + net/xdp/xsk_buff_pool.c | 7 ++++-- tools/include/uapi/linux/if_xdp.h | 1 + 9 files changed, 28 insertions(+), 23 deletions(-) -- 2.53.0-Meta
