Atheros wrote a vendor driver called otus for ar9170 devices, this was prior to the change of focus on working upstream. Atheros then released code and gave specs, etc to a community developer who wrote a proper mac80211 driver for ar9170. The main focus for development today is ar9170. I believe ar9170 does not yet have AMPDU aggregation enabled by default so otus is still available including the stock kernel under drivers/staging area until ar9170 matches all features provided by otus, Read each drivers's wiki page, the section regarding ar9170 and 11n support is very outdated, I know Chris has worked hard on this area. http://wireless.kernel.org/en/users/Drivers/otus http://wireless.kernel.org/en/users/Drivers/ar9170 I have a feeling not enough people know about the wireless wiki...
