WirelessRebootPassphrase
This 9-byte UDS passphrase is sent by the DLP host application to the DLP clients via DLPSRVR:SendWirelessRebootPassphrase. The dlplay client system-application then loads it via DLP:GetWirelessRebootPassphrase for setting the NS WirelessRebootInfo. Afterwards once launched, the DLP child application can then use APT:GetWirelessRebootInfo to load that data.
The last byte in this passphrase is presumably the NUL-terminator. Normally this a randomly-generated ASCII hex string, however it can be arbitrary. Some titles use strings which are less than the max size. This is the passphrase for the new UDS network which will be used by the clients and host for communicating, once the DLP child titles on those clients launch.
