| Description: | |
| The file is avaliable when using a secure concatanation | |
| connection to a NVMe target. Reading the file will return | |
| the serial of the currently negotiated key. | |
| Writing 0 to the file will trigger a PSK reauthentication | |
| (REPLACETLSPSK) with the target. After a reauthentication | |
| the value returned by tls_configured_key will be the new | |
| serial. |
