+Subject: [PATCH 7/8] WNM: Ignore WNM-Sleep Mode Response without pending
+ request
+
+Commit 03ed0a52393710be6bdae657d1b36efa146520e5 ('WNM: Ignore WNM-Sleep
+Mode Response if WNM-Sleep Mode has not been used') started ignoring the
+response when no WNM-Sleep Mode Request had been used during the
+association. This can be made tighter by clearing the used flag when
+successfully processing a response. This adds an additional layer of
+protection against unexpected retransmissions of the response frame.
