From 2104f41a613c67f4de7e2fa6511f19f990fe17c4 Mon Sep 17 00:00:00 2001 From: Javier Cardona Date: Wed, 4 May 2011 17:24:56 +0000 Subject: [PATCH] cfg80211: Use capability info to detect mesh beacons. Mesh beacons no longer use all-zeroes BSSID. Beacon frames for MBSS, infrastructure BSS, or IBSS are differentiated by the Capability Information field in the Beacon frame. A mesh STA sets the ESS and IBSS subfields to 0 in transmitted Beacon or Probe Response management frames.
