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 change the function call signature via adding a pointer value argument for providing the RSS hash type. Patchset also removes all bpf_printk's from xdp_hw_metadata program that we expect driver developers to use. Instead counters are introduced for relaying e.g. skip and fail info. --- Jesper Dangaard Brouer (6): selftests/bpf: xdp_hw_metadata remove bpf_printk and add counters xdp: rss hash types representation mlx5: bpf_xdp_metadata_rx_hash add xdp rss hash type veth: bpf_xdp_metadata_rx_hash add xdp rss hash type mlx4: bpf_xdp_metadata_rx_hash add xdp rss hash type selftests/bpf: Adjust bpf_xdp_metadata_rx_hash for new arg drivers/net/ethernet/mellanox/mlx4/en_rx.c | 22 ++++++- drivers/net/ethernet/mellanox/mlx4/mlx4_en.h | 3 +- .../net/ethernet/mellanox/mlx5/core/en/xdp.c | 63 ++++++++++++++++++- drivers/net/veth.c | 10 ++- include/linux/mlx5/device.h | 14 ++++- include/linux/netdevice.h | 3 +- include/net/xdp.h | 47 ++++++++++++++ net/core/xdp.c | 10 ++- .../selftests/bpf/prog_tests/xdp_metadata.c | 2 + .../selftests/bpf/progs/xdp_hw_metadata.c | 42 +++++++------ .../selftests/bpf/progs/xdp_metadata.c | 6 +- .../selftests/bpf/progs/xdp_metadata2.c | 7 ++- tools/testing/selftests/bpf/xdp_hw_metadata.c | 10 ++- tools/testing/selftests/bpf/xdp_metadata.h | 4 ++ 14 files changed, 205 insertions(+), 38 deletions(-) --
