Loopback is unsupported

[linin00]

Hi，I am asking why setsockopt with IP_MULTICAST_LOOP is unsupported. I noticed that I can use exanic-config to enable local-loopback mode, but when configured to local-loopback mode traffic is disabled from coming in from the wire.

I want to send and recv at the same host at the same time.Thanks for answer
