From cd8f7cb4e6dfa4ea08fc250a814240b883ef7911 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 22 Jan 2013 12:34:29 +0100 Subject: cfg80211/mac80211: support reporting wakeup reason When waking up from WoWLAN, it is useful to know what triggered the wakeup. Support reporting the wakeup reason(s) in cfg80211 (and a pass-through in mac80211) to allow userspace to know.
