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 <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
