--- Comment #100 from Adrian Chadd <adrian@freebsd.org> ---
when you're down there, can you do an "ifconfig -v wlan0 list scan", or
"ifconfig wlan0 -v list scan" (I forget which), and "ifconfig -v wlan0" to get
a full dump of the scan data and the NIC state? That way I can try to reproduce
it with an open AP here.

I'm specifically interested in the protocol handling. I have a feeling that
enabling 11n/11ac/11ax in wpa_supplicant may be clashing with some stuff done
in net80211, but the only real way to see what's going on there is to try and
set it up here to reproduce it.

And cy@, yeah, I can throw you a mini-pcie AR9285. I have squillions of them
here. :) They're a good test case for 1x1 + STBC (and AR9485, which is 1x1 +
STBC + LDPC) which can quite often get mucked up with negotiation nonsense.
