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