Tue 25 Aug 2015 05:19:29 AM UTC, comment #3: Sorry, I think I didn't make myself clear enough: I thought about sending loopback traffic over the real netif (the wifi netif, in your case). This currently fails when the real netif's link is down. I thought it might be handy if loopback traffic would still work in that case.

I've put together a patch that enables multicast support on the loopback netif (127.0.0.1) by setting the NETIF_FLAG_IGMP.
