I see the regression on my WPEA-127N systems as well.

With the patch applied to 3.3.1, I see never ending stream of
auth timeouts (this log is watching 'iw event' output)

power-management is OFF on my system, and using nohwcrypt,
in case that matters.

This is with 10 virtual stations.

I reverted the patch and then it associates immediately.

Occasionally, I would see things associate and run OK with the patch
in place, but it always took a lot of re-tries to associate
even when it did work.

I can easily test patches or try things if anyone has any ideas.

Thanks,
Ben
