From: Shay Drory Introduce MLX5_FLOW_DESTINATION_TYPE_VHCA_RX as a new flow steering destination type. Wire the new destination through flow steering command setup by mapping it to MLX5_IFC_FLOW_DESTINATION_TYPE_VHCA_RX and passing the vhca id, extend forward-destination validation to accept it, and teach the flow steering tracepoint formatter to print rx_vhca_id.
