From 2a4ffa4c8934bd9a36c8354a4b87a529114baf62 Mon Sep 17 00:00:00 2001 From: Javier Cardona Date: Tue, 1 May 2012 03:01:28 -0700 Subject: [PATCH] mac80211_hwsim: Fix rate control by correctly reporting transmission counts Drivers need to report the number of transmission attempts for each rate as well as to terminate the rate array with -1. The in-kernel datapath of hwsim simulates a perfect medium, therefore the driver only needs to report that the first transmission attempt was sucessfully completed at the most favorable rate. Rate control is working again for this driver. Tested mesh mode with minstrel. Signed-off-by: Javier Cardona Signed-off-by: John W.
