Subject: cxgb3: No need to wake queue in xmit handler
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0d9a40de60a4470777913d8d42044ae548e6545d;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

cxgb3: No need to wake queue in xmit handler

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.
