Summary: Callback for M-SEARCH message

Initial Comment:
Would you please add some code for UPnP CD to get a callback when SSDP discovery message reaches and before UPnP SSDP replys.

When UPnP CP is in 168.219.0.0/255.255.255.0 network and UPnP CD is in Auto-IP(169.254.0.0/255.255.0.0;) network, UPnP CD can receive SSDP discovery message from UPnP CP but UPnP CD fails to send SSDP discovery response message because SSDP discovery message is a multicast but SSDP discovery response message is a unicast and there is no route to 168.219.0.0/255.255.255.0. So, I'd like to get a chance to modify routing table before send SSDP discovery response to solve this problem.

Luke,

If you want, you can send a patch for evaluation, we currently have no
resources to code user requests.

Anyway, I don't think this is the correct approach. Both devices must be
on the same network, what you suggest sounds more like a hack to make it
work. Either put CP in the Auto-IP network too by configuring one interface
to an address in this network, or even better, create an alias for this
interface in the Auto-IP network, or somehow put CD in the correct network,
not in the Auto-IP.

Regards,
Marcelo.
