Please do not apply this yet.  As far as I can tell, either
of these patches breaks multiple VIF scenarios.  I'm not
sure exactly why, but I had to revert this to get any
of my interfaces to associate.

I'm using software encryption in case that matters.

Senthil:  Any chance you could test with a few VIFS to
see if you see the same problem?

Here is a dmesg snippet from wireless-testing with the v1 reverted
and v2 applied:
