19 * By default rndis_signal_disconnect does not send status message about
20 * RNDIS disconnection to USB host (indicated as cable disconnected).
21 * Define RNDIS_COMPLETE_SIGNAL_DISCONNECT to send it.
22 * However, this will cause 1 sec delay on Ethernet device halt.
23 * Usually you do not need to define it. Mostly usable for debugging.
