IB/core: Add link layer property to ports
This patch allows ports to have different link layers: IB_LINK_LAYER_INFINIBAND or IB_LINK_LAYER_ETHERNET. This is required for adding IBoE (InfiniBand-over-Ethernet, aka RoCE) support. For devices that do not provide an implementation for querying the link layer property of a port, we return a default value based on the transport: RMA_TRANSPORT_IB nodes will return IB_LINK_LAYER_INFINIBAND and RDMA_TRANSPORT_IWARP nodes will return IB_LINK_LAYER_ETHERNET.
