Constants
       NVMF_AUTH_RCODEEX_FAILED
                   Authentication failed: authentication of the involved host
                   or NVM subsystem failed

       NVMF_AUTH_RCODEEX_PROTOCOL_NOT_USABLE
                   Authentication protocol not usable: the protocol
                   descriptors proposed by the host do not satisfy the
                   security requirements of the controller

       NVMF_AUTH_RCODEEX_SCC_MISMATCH
                   Secure channel concatenation mismatch: the SC_C value
                   specified by the host does not satisfy the security
                   requirements of the controller

       NVMF_AUTH_RCODEEX_HASH_NOT_USABLE
                   Hash function not usable: the HashIDList proposed by the
                   host does not satisfy the security requirements of the
                   controller

       NVMF_AUTH_RCODEEX_KXGROUP_NOT_USABLE
                   Key exchange group not usable: the KXgIDList proposed by
                   the host does not satisfy the security requirements of the
                   controller

       NVMF_AUTH_RCODEEX_INCORRECT_PAYLOAD
                   Incorrect payload: the payload of the received message is
                   not correct

       NVMF_AUTH_RCODEEX_INCORRECT_MESSAGE
                   Incorrect protocol message: the received message is not the
                   expected next message in the authentication protocol
                   sequence
