Can you please try the following patch?

It should fix your problem.
The real problem that I can then address in net-next is the fact that
the Linux bridge tries to be smart and only resorts to flooding
unregistered multicast packets in case its querier is disabled and in
case it didn't detect any other querier in the network. This isn't
currently reflected to underlying drivers. Only mcast snooping on/off.
Anyway, it's not related to the patch in question. You'd get the same
behavior with VLAN-aware bridges.

Didn't understand the question. Can you clarify?
