From: Alex Vesker <redacted> To support passing child interfaces to the lower device a new rdma_netdev function was used, set_id. This will allow us to attach the PKEY index lower device resources such as TIS/QP. For devices that do not support offloads in IPoIB same logic will be used, setting the PKEY index to priv struct.
