First patch fix RX hashing for igc in general. Last patch change test program xdp_hw_metadata to track more timestamps, which helps us correlate the hardware RX timestamp with something. --- To maintainers: I'm uncertain which git tree this should be sent against. This is primary NIC driver code (net-next), but it's BPF/XDP related (bpf-next) via xdp_metadata_ops. Jesper Dangaard Brouer (5): igc: enable and fix RX hash usage by netstack igc: add igc_xdp_buff wrapper for xdp_buff in driver igc: add XDP hints kfuncs for RX hash igc: add XDP hints kfuncs for RX timestamp selftests/bpf: xdp_hw_metadata track more timestamps drivers/net/ethernet/intel/igc/igc.h | 35 ++++++ drivers/net/ethernet/intel/igc/igc_main.c | 116 ++++++++++++++++-- .../selftests/bpf/progs/xdp_hw_metadata.c | 4 +- tools/testing/selftests/bpf/xdp_hw_metadata.c | 47 ++++++- tools/testing/selftests/bpf/xdp_metadata.h | 1 + 5 files changed, 186 insertions(+), 17 deletions(-) --
