From 138ab2e44e99a9544aad60cf137b8ac1f54131c5 Mon Sep 17 00:00:00 2001 From: Vasanthakumar Thiagarajan Date: Sat, 10 Jan 2009 17:07:09 +0530 Subject: [PATCH] ath9k: Fix basic connectivity issue This patch temporarily fixes a regression introduced by BT coexistence support. There is an instability in connection when BT coexistence is enabled on some h/w. This interim fix introduces a module parameter for BT coexistence configuration.
