From bfc32e6a9559d3e30925929cd9a9df7498f325db Mon Sep 17 00:00:00 2001 From: Javier Cardona Date: Mon, 17 Aug 2009 17:15:55 -0700 Subject: mac80211: Decouple fail_avg stats used by mesh from rate control algorithm. Mesh uses the tx failure average to compute the (m)path metric. This used to be done inside the rate control module. This patch breaks the dependency between the mesh stack and the rate control algorithm. Mesh will now work independently of the chosen rate control algorithm. The mesh stack keeps a moving average of the average transmission losses for each mesh peer station. If the fail average exceeds a certain threshold, the peer link is marked as broken.
