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.

V6:
- Resend: selftest failure is unrelated (in xdp_do_redirect)
Issue in fccca038f300 ("veth: take into account device reconfiguration for xdp_features flag")
V5:
- Fixes for checkpatch.pl
- Change function signature for all xmo_rx_hash calls
Jesper Dangaard Brouer (5):
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
