From 23e370989c3fe6b9b2062d9d511feda800434de3 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Sun, 1 Mar 2015 09:10:08 +0200 Subject: [PATCH] mac80211: start queues if driver rejected wowlan If the driver rejects WoWLAN, restart the queues before returning to cfg80211. cfg80211 will return to mac80211, but not before it disconnects all interfaces. If we don't start the queues, any of the packets needed for disconnecting won't be transmitted, which is strange. Fix that.
