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. |
