Subject[PATCH 4.14 094/496] cfg80211: clear wep keys after disconnection
Date
4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Avraham Stern <avraham.stern@intel.com>

[ Upstream commit 3027a8e799b20fc922496a12f8ad2f9f36a8a696 ]

When a low level driver calls cfg80211_disconnected(), wep keys are
not cleared. As a result, following connection requests will fail
since cfg80211 internal state shows a connection is still in progress.

Fix this by clearing the wep keys when disconnecting.
