Johannes Berg 054c9939b4 mac80211: pause TX while changing interface type ... syzbot reported a crash that happened when changing the interface type around a lot, and while it might have been easy to fix just the symptom there, a little deeper investigation found that really the reason is that we allowed packets to be transmitted while in the middle of changing the interface type. Disallow TX by stopping the queues while changing the type.
