From b1ad1b6febb7772583c98d9a879fbbdb82a726a7 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Sat, 9 Apr 2011 23:10:21 +0200 Subject: ath5k: fix slot time handling Set the slot time based on the mac80211 short slot vs long slot setting instead of just forcing long slot for all CCK-enabled channels. This slightly improves 802.11g mode performance in in my tests. Signed-off-by: Felix Fietkau Signed-off-by: John W.
