22 | Subject: [PATCH 7/8] WNM: Ignore WNM-Sleep Mode Response without pending | ||
23 | request | ||
24 | |||
25 | Commit 03ed0a52393710be6bdae657d1b36efa146520e5 ('WNM: Ignore WNM-Sleep | ||
26 | Mode Response if WNM-Sleep Mode has not been used') started ignoring the | ||
27 | response when no WNM-Sleep Mode Request had been used during the | ||
28 | association. This can be made tighter by clearing the used flag when | ||
29 | successfully processing a response. This adds an additional layer of | ||
30 | protection against unexpected retransmissions of the response frame. | ||
