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.
