The code is a mess -- look at how much code I remove below (and that's
after everybody elses cleanups!) for a dubious optimisation.

I agree that we should address this and we need to really do this to not
mess up our aggregation state, but the current code is too complex and
causing too many issues. We also need to think about this in the context
of multi-virtual-channel support.

Well crap.  Why don't you try to fix it right instead?

I'll probably end up carrying this in my own tree so
that multiple vifs work well and don't constantly
reset the ath9k causing it to shit itself...

Given the auth/assoc redesign that went in now, are you still carrying
this? Does the redesign address your problem?

I haven't looked yet...still stuck back on 3.0 kernel for the
most part.

I should be moving to 3.3 sometime soon, and will see how it works.

I was thinking that I would ignore the work logic for now and probably
just focus on re-applying the on-channel scan optimization first.

Are you done, or mostly done with the re-architecture you were working on?

I know you didn't like the scan optimization from before...do you have any
ideas on how it might be done more to your liking?

Thanks,
Ben
