Hi Vlad,

This is not a comment for this patch set, but I have a question.

I'm trying to use bridge command to turn off flood/learning but couldn't
find the corresponding command.
I'm expecting something like "bridge link set br0 flood/learning".

Are there any other userspace commands that can set flood/learning flag?

Thanks,
Toshiaki Makita
