The problem I see is that there is no good way to trigger a DHCP renew from a network device drivers. You're on the wrong layer. 10 seconds may work but this is IMHO a hack which can easily break. There are also more networking implementations than ifplugd. Specially the systemd implementation looks promising. Can't you propagate the RNDIS_STATUS_NETWORK_CHANGE event to userspace? IIRC on HyperV guests already have a guest daemon. Let the daemon handle the event such that distros can install their own hooks...
