What you really "want" is to use VHT modulations, mostly for the

I think the de-facto standard for this would be to use IEs similar to
VHT ones, encapsulated in some (Broadcom?) vendor IE. We may have to
work with that, but that's not what this patch does. Jouni had some
better idea how this worked, I think.
hostapd has code to negotiate this using the vendor specific element. I
think we ended up getting this working with AP side (i.e., ath10k on the
AP) and if I've understood correctly, this does not need any additional
changes on top of what is available in upstream kernel and hostapd.
Station mode is something that may have been left open since this issue
of what and how to advertise as capabilities came up and there was not
strong enough push at the time to get more than AP side functional..
Hostapd and supplicant did not need any changes in my testing.
But, you *have* to modify the kernel or it will disable VHT no matter
what supplicant says...
Thanks,
