[PATCH 1/1] iwlwifi: don't perform "echo test" when cmd queue stuck
From: Guy, Wey-Yi W
Date: Thu Oct 27 2011 - 21:33:38 EST
From: Wey-Yi Guy <wey-yi.w.guy@xxxxxxxxx>
Perform "echo test" when cmd queue stuck detected, somethime it will cause
calltrace. I am not sure how to fix it yet, just remove the action now until
find a better way to handle it.
