   3 Subject: [PATCH] brcmfmac: Add wowl wake indication report.
   4
   5 On wakeup of the system (resume) a wowl wakeup indication report
   6 can be sent to cfg80211. This patch adds support for this. The
   7 report specifies if the device was responsible for the wakeup
   8 and if so, will specify the exact reason.
