From 22de94de7de78b8de2fb1f2df5aa85b5556cfcfd Mon Sep 17 00:00:00 2001 From: Stanislaw Gruszka Date: Fri, 3 Dec 2010 15:41:48 +0100 Subject: iwlwifi: jiffies based tx queues watchdog This patch replace monitor/recover timer by watchdog based on time stamp. New code allow to discover hangs more precisely. Timeout values are currently doubled monitoring period values of previous timer. This have to be tuned based of firmware timing capabilities. Tested on 3945, 4965, 5300, 6300. Signed-off-by: Stanislaw Gruszka Acked-by: Wey-Yi Guy Signed-off-by: John W.
