From eecc48000afe2ca6da22122d553b7cad294e42fc Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 4 May 2011 15:37:29 +0200 Subject: mac80211: add basic support for WoWLAN This adds basic support for the new WoWLAN configuration in mac80211. 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.
