From 2b4562dfd6ad3579951de21168cb9d266ed3f1bd Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Sat, 2 Jul 2011 00:02:01 +0200 Subject: mac80211: allow driver to impose WoWLAN restrictions If the driver can't support WoWLAN in the current state, this patch allows it to return 1 from the suspend callback to do the normal deconfiguration instead of using suspend/resume calls. Note that if it does this, resume won't be called. Signed-off-by: Johannes Berg Signed-off-by: John W.
