hi! With my latest stuff landed in -HEAD, the rtwn driver can now transmit VHT rates. The rate control (AMRR) is just as terrible at VHT as it is at HT, but it works enough to demonstrate it works.
If you're running -HEAD and have an RTL8812AU/RTL8821AU NIC lying around, I would appreciate you testing it out! There's still a bunch of sharp/dull corners around this - notably there's no way to configure static VHT transmit rates via ifconfig right now - but the pieces ARE there if someone wants to take a crack at it. Thanks again! -adrian
