From a6fe231361e35e3d068a63bbfd2318fa4e961ec5 Mon Sep 17 00:00:00 2001 From: Juuso Oikarinen Date: Fri, 11 Dec 2009 15:40:58 +0200 Subject: [PATCH] wl1271: Use slow rates for association messages While not associated, default the data rates to 1 and 2mbps, so that only those rates will be used for association related message transfer. Once associated, configure the full rate-set supported by the AP. Signed-off-by: Juuso Oikarinen Reviewed-by: Luciano Coelho Signed-off-by: Luciano Coelho Signed-off-by: John W.
