Hi Markus, Generally, this seems fine. I have applied the cfg80211/nl80211 bits in my tree (currently in mac80211-next pending branch), and recombined the patches for that. I've also modified the nl80211 code to return the cookie in the extack message, rather than a separate message, which is much nicer. That means you'll have to modify the hostapd changes for this. The mac80211 changes seem overly complex, I'll reply in detail. johannes
