Current API for bpf_xdp_metadata_rx_hash() returns the raw RSS hash value, but doesn't provide information on the RSS hash type (part of 6.3-rc). This patchset proposal is to use the return value from bpf_xdp_metadata_rx_hash() to provide the RSS hash type. --- Jesper Dangaard Brouer (4): xdp: rss hash types representation igc: bpf_xdp_metadata_rx_hash return xdp rss hash type veth: bpf_xdp_metadata_rx_hash return xdp rss hash type mlx5: bpf_xdp_metadata_rx_hash return xdp rss hash type drivers/net/ethernet/intel/igc/igc_main.c | 22 ++++++- .../net/ethernet/mellanox/mlx5/core/en/xdp.c | 61 ++++++++++++++++++- drivers/net/veth.c | 2 +- include/linux/mlx5/device.h | 14 ++++- include/net/xdp.h | 54 ++++++++++++++++ net/core/xdp.c | 4 +- 6 files changed, 150 insertions(+), 7 deletions(-) --
