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?
