SubjectRe: [PATCH 2/2] ipv4: make do_ip_setsockopt for IP_MULTICAST_IF support ip_mreq struct

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));

Best Regards
Shan Wei
