According to
http://ozlabs.org/pipermail/linuxppc-embedded/2005-May/018529.html
it would seem that multicast is not correctly implemented and has been
effectively commented out. This also stops promisc mode working. I
have removed the return in my source tree and promisc mode now works
fine. I can't say whether multicast works. Maybe you could just give it
a try and see what happens....
