From eadac6bf95e1945bb64e6f8f22d8509391645e2e Mon Sep 17 00:00:00 2001 From: Arnd Hannemann Date: Mon, 24 Aug 2009 20:51:46 +0200 Subject: [PATCH] mac80211: Fix output of minstrels rc_stats An integer overflow in the minstrel debug code prevented the throughput to be displayed correctly. This patch fixes that, by permutating operations like proposed by Pavel Roskin. Signed-off-by: Arnd Hannemann Signed-off-by: John W.
