From b8b93985bfe32da1230ec77c75dde398a0c3b142 Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>

Subject: [PATCH] mac80211: fix authentication with iwlwifi/mvm
The original patch didn't copy the ieee80211_is_data() condition
because on most drivers the management frames don't go through
this path. However, they do on iwlwifi/mvm, so we do need to keep
the condition here.
Cc: stable@vger.kernel.org
Fixes: ce2e1ca70307 ("mac80211: Check port authorization in the ieee80211_tx_dequeue() case")
