It allows to report GEOM::lunid for nda(4) same as for nvd(4). Since NVMe now allows multiple LUs (namespaces) with multiple paths unique LU identification is important. The serial_num field is filled same as before with the controller serial number, while device_id is based on namespace GUID and/or EUI64 fields as recommended by "NVM Express: SCSI Translation Reference" and matching nvd(4) at the end.
