mlx5: bpf_xdp_metadata_rx_hash add xdp rss hash type
Update API for bpf_xdp_metadata_rx_hash() with arg for xdp rss hash type
via mapping table.
The mlx5 hardware can also identify and RSS hash IPSEC. This indicate
hash includes SPI (Security Parameters Index) as part of IPSEC hash.
Extend xdp core enum xdp_rss_hash_type with IPSEC hash type.
Fixes: bc8d405b1ba9 ("net/mlx5e: Support RX XDP metadata")
