From ff1b6e69ad4f31fb3c9c6da2665655f2e798dd70 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 4 May 2011 15:37:28 +0200 Subject: nl80211/cfg80211: WoWLAN support This is based on (but now quite far from) the original work from Luis and Eliad. Add support for configuring WoWLAN triggers, and getting the configuration out again. Changes from the original patchset are too numerous to list, but one important change needs highlighting: the suspend() callback is passed NULL for the trigger configuration if userspace has not configured WoWLAN at all.
