From 40990ec01fcca0b86a19c13a5d3deb77da1913a7 Mon Sep 17 00:00:00 2001 From: Sujith Date: Sun, 7 Dec 2008 21:41:37 +0530 Subject: ath9k: Fix bug in rate table management The proper rate table wouldn't be used if a disassoc happens and a new attempt is made to associate using wpa_supplicant. This patch fixes it by storing the rate table to be used on association. Signed-off-by: Sujith Signed-off-by: John W.
