Constants

       NVME_CTRL_FNA_FMT_ALL_NAMESPACES
                   If  set,  then all namespaces in an NVM subsystem shall be configured with the
                   same attributes and a format (excluding secure erase) of any namespace results
                   in  a  format  of  all  namespaces  in  an NVM subsystem. If cleared, then the
                   controller supports format on a per namespace basis.

       NVME_CTRL_FNA_SEC_ALL_NAMESPACES
                   If set, then any secure erase performed as part of a format operation  results
                   in a secure erase of all namespaces in the NVM subsystem. If cleared, then any
                   secure erase performed as part of a format results in a secure  erase  of  the
                   particular namespace specified.

       NVME_CTRL_FNA_CRYPTO_ERASE
                   If  set, then cryptographic erase is supported. If cleared, then cryptographic
                   erase is not supported.

       NVME_CTRL_FNA_NSID_FFFFFFFF
                   If set, then format does not support nsid value set to FFFFFFFFh. If  cleared,
                   format supports nsid value set to FFFFFFFFh.
