I think that the problem is that if no querier are available on the network, the switchs should forward to all ports by default.

Now, if before we have querier from linux bridge, maybe physical switchs have made igmp group.
And removal of the querier on linux bridge make the switches stop forwarding.


I'll write somes informations on the wiki in multicast doc for cisco users or people who's want to disable querier.

Thank. I applied a slightly different version (0005-bridge-disable-querier.patch) 
Bad name for this patch series. 

The bad think with multicast_querier disabled is that it works sometimes, sometimes not. 
Behavior is not really reproducible (when multicast_querier is also disabled on the switch).
