Subject: [dts] [PATCH V4 1/1] [examples/flow_classify]: upload automation test script
Date: Fri, 20 Sep 2019 10:21:51 +0800
Message-ID: <20190920022151.11817-2-yufengx.mo@intel.com> (raw)
In-Reply-To: <20190920022151.11817-1-yufengx.mo@intel.com>


This automation test script is for flow classify feature.
flow_classify is the tool to call flow_classify lib for group of packets,
just after receiving them or before transmitting them.
