Subject: [RFC v2 12/12] mac80211: report OBSS beacons
Date: Fri, 21 Oct 2011 16:23:34 +0200 [thread overview]
Message-ID: <20111021142430.304482399@sipsolutions.net> (raw)
In-Reply-To: 20111021142322.229128720@sipsolutions.net
From: Johannes Berg <johannes.berg@intel.com>
If there's an interface in AP mode, OBSS beacons
are needed by hostapd/wpa_s to implement logic to
enable/disable protection etc. Report the frames
and set the capability flag.
