Before I initially contacted the mailing list, I noticed that wpa_s
defaults to HT20 mode while iw does not default to HT mode, so I
enabled HT mode on the end configured with iw.  Alas, it didn't fix
the issue.

Setting user_mpm = 0 didn't work.  Below is a piece of the output from
wpa_s.  I'm still working on that pcap.  I'll get it as soon as I can.
Thanks for the support.
