Makes sense.

Not familiar with that issue - I'll prowl the list.

Ok. So there is a toggle somewhere which controls how flooding should

You make a reasonable arguement to have it in the kernel but i think we
win more if we separate the control. So while i empathize, I am hoping
that youd go with the path that is hard to travel ;->

Hrm - hadnt paid attention to that before. Nasty.
The bridge seems to be hard-coding policy on station movement, no?
