From 8e532175277d9a5eae49768ed086555081f741a7 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Mon, 4 May 2009 18:04:55 +0200 Subject: [PATCH] mac80211: minstrel, fix memory corruption minstrel doesn't count max rate count in fact, since it doesn't use a loop variable `i' and hence allocs space only for bitrates found in the first band. Fix it by involving the `i' as an index so that it traverses all the bands now and finds the real max bitrate count. Signed-off-by: Jiri Slaby Cc: Felix Fietkau Signed-off-by: John W.
