| 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. |
