I've put together a patch that enables multicast support on the loopback netif
( by setting the NETIF_FLAG_IGMP.

My patch also adds a configuration option LWIP_LOOPIF_MCAST which defaults to
off in opt.h to control this behavior

I'm using multicast on the loopif to support mDNSResponder performing
same-machine communication when no real netifs are up
