4 Subject: [PATCH 7/8] WNM: Ignore WNM-Sleep Mode Response without pending
5 request

7 Commit 03ed0a52393710be6bdae657d1b36efa146520e5 ('WNM: Ignore WNM-Sleep
8 Mode Response if WNM-Sleep Mode has not been used') started ignoring the
9 response when no WNM-Sleep Mode Request had been used during the
10 association. This can be made tighter by clearing the used flag when
11 successfully processing a response. This adds an additional layer of
12 protection against unexpected retransmissions of the response frame.
