I'm a bit late in the conversation. Isn't this what you want?

    ip address add <multicast IPv4 address> dev br0 autojoin

Not really, I was looking in a way to register the ports to link layer
multicast address. Sorry for the confusion, my description of the patch
was totally missleaning.

If you follow this thread you will get a better idea what we wanted to
achive. We got some really good comments and based on these we send a
RFC[1]. 

Thanks,
Vivien
