After some discussion offline with Christoph Lameter and David Stevens regarding multicast behaviour in Linux, I'm submitting a slightly modified patch from the one Christoph submitted earlier. This patch provides a new socket option IP_MULTICAST_ALL. In this case, default behaviour is _unchanged_ from the current Linux standard. The socket option is set by default to provide original behaviour. Sockets wishing to receive data only from multicast groups they join explicitly will need to clear this socket option.
