Also, I know I've already mentioned this...but...the scan function really needs to be addressed...

It's completely nearly fully of facepalm.

No idea. :)

Lot's of reasons. DMA taking too long, TX engine is stuck, RX CLEAR is
stuck low, the medium is too busy, calibration is taking too long,

No idea? :) "6" should be an OFDM rate, same as 12. Maybe there's
something going on with power calibration in the AR5212 series NICs
that needs the higher rates to be used?
(Since the earlier nics use PAPRD test frames to calibrate the output TX.)
