Constants

19       NVME_CTRL_FNA_FMT_ALL_NAMESPACES
20                   If set, then all namespaces in an NVM  subsystem  shall  be
21                   configured with the same attributes and a format (excluding
22                   secure erase) of any namespace results in a format  of  all
23                   namespaces  in  an NVM subsystem. If cleared, then the con‐
24                   troller supports format on a per namespace basis.
25
26       NVME_CTRL_FNA_SEC_ALL_NAMESPACES
27                   If set, then any secure erase performed as part of a format
28                   operation  results  in  a secure erase of all namespaces in
29                   the NVM subsystem. If cleared, then any secure  erase  per‐
30                   formed as part of a format results in a secure erase of the
31                   particular namespace specified.
32
33       NVME_CTRL_FNA_CRYPTO_ERASE
34                   If set, then cryptographic erase is supported. If  cleared,
35                   then cryptographic erase is not supported.
36
37       NVME_CTRL_FNA_NSID_FFFFFFFF
38                   If  set,  then  format  does  not support nsid value set to
39                   FFFFFFFFh. If cleared, format supports nsid  value  set  to
40                   FFFFFFFFh.
