    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.
