           NVME_NS_DLFEAT_RB ,
           NVME_NS_DLFEAT_RB_NR ,

Constants

       NVME_NS_DLFEAT_RB
                   Mask to get the value of the read behavior

       NVME_NS_DLFEAT_RB_NR
                   Read behvaior is not reported

       NVME_NS_DLFEAT_RB_ALL_0S
                   A deallocated logical block returns all bytes cleared to 0h.

       NVME_NS_DLFEAT_RB_ALL_FS
                   A deallocated logical block returns all bytes set to FFh.

       NVME_NS_DLFEAT_WRITE_ZEROES
                   If set, indicates that the controller supports the Deallocate bit in the Write
                   Zeroes command for this namespace.

       NVME_NS_DLFEAT_CRC_GUARD
                   If  set,  indicates  that  the Guard field for deallocated logical blocks that
                   contain protection information is set to the CRC for the value read  from  the
                   deallocated logical block and its metadata
