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.
