Linux Ethernet Bridging - Apr 2023 - [Bridge] VLAN-aware multicast querier after if link up

Hi Nikolay,

I'd like your input on an issue I'm running into at the moment.

I setup a bridge to do multicast querying for some vid. This then does 
not work for ports that come up later. It works only for those ports 
that were already up when I set the global vlan options.

Debugging through the kernel I can see that the timers are simply never 
started. Unless I disable and re-enable the querier for that particular vid.

Admittedly, I'm working with 5.15 at the moment. But even on mainline, I 
do not see any relevant changes that would make this work.

I have a simple-ish patch, but I'm wondering whether I'm missing 
something? Is maybe some action from userspace expected when a port 
comes up?

Best
Dennis Hamester
