Hello, You said: You first need to add support for uAPSD to mac80211 for drivers which need this completely in software, and then add it to ath9k. Sorry, but I don't understand. What do you add to mac80211.h? What do you add to ath9k? Can you explain step by step how to enable UAPSD on ATH9k or other one driver please? I use iw like userspace. It is not possible to define uapsd parameter in order to set or get value like iwpriv. This case will help many people who want to add parameter because it very difficult fo find something.
