Constants

Shift amount to get the format applied to all namespaces
Shift amount to get the secure erase applied to all namespaces
Shift amount to get the cryptographic erase supported
Shift amount to get the format supported an NSID FFFFFFFFh
Mask to get the format applied to all namespaces
Mask to get the secure erase applied to all namespaces

Mask to get the format supported an NSID FFFFFFFFh
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.
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.
If set, then cryptographic erase is supported. If cleared, then cryptographic erase is not supported.
If set, then format does not support nsid value set to FFFFFFFFh. If cleared, format supports nsid value set to FFFFFFFFh.
