The kernel never generates IGMP control traffic related to routing. Any IGMP traffic generated by userland, generally uses the raw socket interface. Userland could potentially also use pcap to inject directly to the link layer, and indeed, that might be a more desirable situation where the daemon is intended to run on interfaces w/o an IPv4 address. Of course, this entirely bypasses the host IP stack. thanks, BMS
