It's not meaning to support the ip_mreq struct, the imr_multiaddr member never be used by the IP_MULTICAST_IF.
In addition, using the option normally like this: struct in_addr interface_addr; setsockopt (socket, IPPROTO_IP, IP_MULTICAST_IF, &interface_addr, sizeof(interface_addr));
Do your patch suggest using the option like this? struct ip_mreq mreq; setsockopt (socket, IPPROTO_IP, IP_MULTICAST_IF, &mreq, sizeof(mreq));
