RDMA/core: Introduce "name_assign_type" for an IB device
The name_assign_type indicates how the name is provided. Currently these types are supported: - RDMA_NAME_ASSIGN_TYPE_UNKNOWN: Unknown or not set; - RDMA_NAME_ASSIGN_TYPE_USER: Name is provided by the user; The user-created sub device, rxe and siw device has this type. When filling nl device info, it is set in the new attribute RDMA_NLDEV_ATTR_NAME_ASSIGN_TYPE. User-space tools like udev "rdma_rename" could check this attribute to determine if this device needs to be renamed or not.
