From 722f069a6dc95d7c6c2cdfbe3413899a3b768f9c Mon Sep 17 00:00:00 2001 From: Sujith Date: Tue, 17 Mar 2009 08:50:06 +0530 Subject: mac80211: Tear down aggregation sessions for suspend/resume When the driver has been notified with a STA_REMOVE, it tears down the internal ADDBA state. On resume, trying to initiate aggregation would fail because mac80211 has not cleared the operational state for that . This can be fixed by tearing down the existing sessions on a suspend. Also, the driver can initiate a new BA session when suspend is in progress. This is fixed by marking the station as being in suspend state and denying ADDBA requests for such STAs.
