Subject: [PATCH] cxgb3: No need to wake queue in xmit handler

From: Krishna Kumar <[email-masked]>
Date: Thu, 15 Oct 2009 11:24:19 +0530

The xmit handler doesn't need to wake the queue after stopping
it temporarily (some other drivers are doing the same).

Patch on net-next-2.6, multiple netperf sessions tested.
