[pve-devel] [PATCH] bridge: disable igmp querier by default

I'll try to have more info from him in the forum.
Maybe all nodes need to be updated to last kernel

I really think it should work for everybody, but maybe the upgrade is not simple.



But if it's really a problem for a lot of people, we can keep the patched kernel, but set igmp query enabled by default in kernel patch.
Cisco users just will need to add a "pre-up echo 0 > /sys/class/brige/../igmp_querier" on their bridge config to disable the feature.

Yep, read that. Hopefully he returns with the message that he is not 
using a Cisco switch;-) If he is using a Cisco switch Alexandre needs 
to dig his Cisco switches configuration:-) 

If this seems to be a thing where Cisco is doing it the opposite way 
than any other manufacture what will be the correct way to handle this? 
1) Revert to the old config and give instructions to Cisco users how to 
turn igmp snooping off on pve hosts 
2) Keep the new kernel an instruct anybody else how to turn igmp 
snooping on on pve hosts 
3) Implement some kind of auto detection script to configure the kernel 
on runtime
