I'll investigate the rate-control logic. I don't know enough
about IBSS currently to know why it would use different rate-ctrl logic than
the normal sta/ap, but hopefully I can figure it out.
Can you post some details on how you configure HT20 v/s legacy mode
for IBSS interfaces?
Do you have any reason to believe the problem is in the driver or mac80211
stack, or is this all a firmware issue?
And, if anyone has a different /AC NIC that can do IBSS, I'm curious
if ath10k will receive at higher speeds?
Thanks,
Ben

For legacy mode, rate control works. rate_idx to 7 or 54Mbps.

Similar to 636 firmware.

I still cannot get WPA2 encryption to work, but open authentication
seems to work fine. I still have a good bit more testing to do.
I cannot get ath9k to do encryption in IBSS mode either, so I
probably am mis-configuring something.
I don't believe WPA2 is supported with adhoc (at least through
wpa_supplicant). However, WPA should be and while testing your
firmware, I found that it doesn't seem to work (They don't see each
other and thus don't associate).
I also found that, like the 999.x firmware, the rate's do not go
higher than 54mbit/s. Is this due to the firmware not advertising
proper rates or..?
Are you joining the adhoc network in non-HT mode? Anyway, even if you
use HT mode, the rate control is not working for 999.x firmware and
always stuck at 6Mbps as far as I know.
