This option causes all multicast sends to be accelerated. When disabled, multicast sends are only accelerated for sockets that have cleared the IP_MULTICAST_LOOP flag.
This option disables loopback of multicast traffic to receivers on the same host, unless (a) those receivers are sharing an Onload stack with the sender (see EF_NAME) and EF_MCAST_SEND is set to 1 or 3, or(b) prerequisites to support loopback to other Onload stacks are met (see EF_MCAST_SEND).
