My system, at least, is dynamic, and I do not want to restart existing
AP vifs if user adds or modifies a second one.  I'm building test equipment,
so doing exactly what the user asks, as much as possible, is more important.

Forcing the system to use the requested channel configuration falls under
this category in my opinion.

Taking local constraints into account would probably be an improvement
either way.  It would at least work more often, even if it doesn't actually
fix *my* case.

I don't know Ann's exact limitations, so possibly what you suggest would work
for her.

Thanks,
