This patch supports driver APIs "add_sub_dev" and "del_sub_dev", to add and delete a plane device respectively. A mlx5 plane device is a rdma SMI device; It provides the SMI capability through user MAD for it's parent, the logical multi-plane aggregated device. For a plane port: - It supports QP0 only; - When adding a plane device, all plane ports are added; - For some commands like mad_ifc, both plane_index and native portnum is needed; - When querying or modifying a plane port context, the native portnum must be used, as the query/modify_hca_vport_context command doesn't support plane port.
