When this option is set to 1, and a UDP socket joins a multicast group on an interface that is not accelerated, the UDP socket is handed-over to the kernel stack. This can be a good idea because it prevents that socket from consuming Onload resources, and may also help avoid spinning when it is not wanted.
When set to 2, UDP sockets that join multicast groups are always handed-over to the kernel stack.
