When tx queue stuck, iwlwifi driver should detect and reload the firmware;
different devices has different timing requirement, change the timeout
value for 5000 series devices to avoid un-necessary firmware reload which
can cause device become unstable.
This fixes:
http://article.gmane.org/gmane.linux.kernel.wireless.general/53552
Those patches already available in wireless-2.6
Wey-Yi Guy (2):
iwlwifi: long monitor timer
iwlwifi: use long monitor timer to avoid un-necessary reload
this patch is also available from wireless-2.6 branch on

Change the name for monitor timer, also adding define for long monitor
timer; long monitor timer can be used for the type of devices require longer
time to determine the uCode is stuck on tx and needed reload.

For 5000 series of devices, use long monitor timer to check
stuck tx queues.
5000 series device, it is being reported firmware got reload more
often than necessary, so extend the timer to avoid un-necessary reload.

What about iwl5300 ?
As I noted in the other thread my 5300 was affected by said issue and
increasing the timeout fixed it.
Looks like an oversight to me.

I am not aware of 5300 also having similar issues; I all submit follow
up patch to extend the timeout value for 5300 device.

Change the name for monitor timer, also adding define for long monitor
timer; long monitor timer can be used for the type of devices require longer
time to determine the uCode is stuck on tx and needed reload.
