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.
