                   should be used by the host for this namespace instead of the AWUN, AWUPF, and ACWU fields  in
                   the Identify Controller data structure.

       NVME_NS_FEAT_DULBE

                   If set, indicates that the value in the NGUID field for this  namespace,  if  non-  zero,  is
                   never  reused  by the controller and that the value in the EUI64 field for this namespace, if
                   non-zero, is never reused by the controller.
