net/mlx5e: Support cross-vhca RSS

Browse Source 
Implement driver support for the HW feature that allows RX steering of
one device to target other device's RQs.

In SD multi-pf netdev mode, we set the secondaries into silent mode,
disconnecting them from the network. This feature is then used to steer
traffic from the primary to the secondaries.
