Yeah, I saw it, but it's not clear to me that there's much point in it. In any case, that's an unrelated question in a way, because there definitely are things happening here that should be "more synchronous", regardless of whether or not the key deletion makes sense. > I think, your cfg80211 change will help.

Right. Care to test my patch before I properly submit it? johannes
