are small cleanups to the network code and could be merged even if multicast support is deemed unnecessary.

Multicast connections are used like any other UDP connection:

    con = net_udp_new(string_to_ip("224.0.0.123"), 12345, handler, priv);
    net_udp_bind(con, 12345);

I only patched the drivers smc91111 (tested) and smc911x (untested) to receive multicast packets. Other drivers are likely just as easy to patch.

Have fun,
	Colin
