please try bwn(4) in -HEAD

[Adrian Chadd]

I can't believe I'm about to say this, but..

.. please try bwn(4) on HEAD. If you have a NIC that does 11a, please
let me know as I have more fixes relating to frame protection and rate
selection that need to go in.

I just fixed a couple of very dumb bugs that prevented the thing from
working except in completely ideal circumstances, which for 2g is
pretty amazingly hard to find these days.

No, I won't port this to stable/10. Someone else is very welcome to
backport bwn(4) fixes to stable/10 and beyond; you don't need my
blessing.
