IB/mlx5: Expose RSS related capabilities
Expose RSS related capabilities on both IB and vendor channels.
In addition to the IB capabilities the driver reports some extra
capabilities on its vendor channel:
- Bit mask of the supported types of hash functions.
- Bit mask of the supported RX fields that can participate
in the RX hashing.
Those capabilities are applicable only when the link layer
is Ethernet.
