Subject: [dpdk-dev] [PATCH v6 5/6] examples/ioat: add stats printing for each port
Date: Mon, 30 Sep 2019 09:50:33 +0200	[thread overview]
Message-ID: <20190930075034.2000-6-marcinx.baran@intel.com> (raw)
In-Reply-To: <20190930075034.2000-1-marcinx.baran@intel.com>

Added printing stats of ports each second.
The stats printing is done using master core.
The information provided informs about packets
received, dropped and send as well as statistics
of rawdev devices.
