From 26d59535aa08386b97ece58a27bb16fca4f066db Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 1 Apr 2011 13:52:48 +0200 Subject: mac80211: clean up station cleanup timer We currently run this timer exactly once when a new mac80211 device is registered, but that is completely pointless since it will have no work to do at all. Therefore, remove that and also simplify some code using the timer. Signed-off-by: Johannes Berg Signed-off-by: John W.

The behaviour is completely offloaded to the driver though, with two new callbacks (suspend/resume). Options for the driver include a complete reconfiguration after wakeup, and exposing all the triggers it wants to support. Signed-off-by: Johannes Berg Signed-off-by: John W.
