Thanks for carrying this forward, Stanislav! :) +1000 -- great work everybody! :-) To Alexander (Cc Jesse and Tony), do you think someone from Intel could look at extending drivers: drivers/net/ethernet/intel/igb/ - chip i210 drivers/net/ethernet/intel/igc/ - chip i225 drivers/net/ethernet/stmicro/stmmac - for CPU integrated LAN ports We have a customer that have been eager to get hardware RX-timestamping for their AF_XDP use-case (PoC code[1] use software timestamping via bpf_ktime_get_ns() today). Getting driver support will qualify this hardware as part of their HW solution. --Jesper [1] https://github.com/xdp-project/bpf-examples/blob/master/AF_XDP-interaction/af_xdp_kern.c#L77

Please see the first patch in the series for the overall design and use-cases. See the following email from Toke for the per-packet metadata overhead: https://lore.kernel.org/bpf/20221206024554.3826186-1-sdf@google.com/T/#m49d48ea08d525ec88360c7d14c4d34fb0e45e798 Recent changes: - Keep new functions in en/xdp.c, do 'extern mlx5_xdp_metadata_ops' (Tariq) - Remove mxbuf pointer and use xsk_buff_to_mxbuf (Tariq) - Clarify xdp_buff vs 'XDP frame' (Jesper) - Explicitly mention that AF_XDP RX descriptor lacks metadata size (Jesper) - Drop libbpf_flags/xdp_flags from selftests and use ifindex instead of ifname (due to recent xsk.h refactoring) Prior art (to record pros/cons for different approaches): - Stable UAPI approach: https://lore.kernel.org/bpf/20220628194812.1453059-1-alexandr.lobakin@intel.com/ -
