Subject: [linux-next] bisected: first bad commit: mac80211: Check port
 authorization in the ieee80211_tx_dequeue() case

Hello,

Commit "mac80211: Check port authorization in the ieee80211_tx_dequeue()
case" breaks wifi on my laptop:

	kernel: wlp2s0: authentication with XXXXXXXXXXXXXX timed out

It just never connects to the network.
