From 562a74803f4881772ba2375ec4e5aa0ad90f4caa Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 7 Nov 2011 12:39:33 +0100 Subject: nl80211: advertise device AP SME Add the ability to advertise that the device contains the AP SME and what features it can support. There are currently no features in the bitmap -- probe response offload will be advertised by a few patches Arik is working on now (who took over from Guy Eilam) and a device with AP SME will typically implement and require response offload.
