I am pretty sure we did this under some kind of Linux, and I think it
was SuSE.

We didn't have any MIMO cards, so you may be simply hitting a minor bug.

The barker code demod defaults to off (probably not a wise choice).
Make sure it's on - I suggest reading the code and the option parsing in
particular.This is all a bit rough.
I definitely received 802.11 packets (1 Mb/s) under NetBSD. So while
I'm sure there are things wrong, it's possible to make it work.
See the tap example; that's what I ran most recently.
