Hm. This is curious. *How* does AP mode fail? You said earlier stations
failed to connect, but can they actually get associated? I'm curious
because while I could see the carrier state thing causing issues (on old
hostapd versions that we didn't test), I'm not sure I see how the skb
payload makes a difference since mac80211 will linearize management
frames (so association should work) and data frames don't matter (so
authorization should work) ... unless there's a bug somewhere in
mac80211 where it forgets to pskb_may_pull(), but I don't see any such
place right now.

I am not sure what happens. In the failure case the high-level symptom
(in NetwokManager or in Windows) is that "failed to set IP address".
I've captured 2 tcpdumps - for the working (those 2 patches reverted)
and non-working cases (vanilla 3.5.4). I'll send them to you privately.
