From 8f2fda9594f083981ad54c1994863875fe680925 Mon Sep 17 00:00:00 2001 From: Rui Paulo Date: Mon, 9 Nov 2009 23:46:41 +0000 Subject: [PATCH] mac80211: implement the meshconf formation info field The Mesh Configuration Formation Info field contains the number of neighbors. This means that the beacon must be updated every time a peer joins or leaves.
