Subject: [dpdk-dev] [PATCH v2 5/6] net/af_xdp: enable zero copy
Date: Tue, 19 Mar 2019 15:12:55 +0800	[thread overview]
Message-ID: <20190319071256.26302-6-xiaolong.ye@intel.com> (raw)
Message-ID: <20190319071255.zTnPE-Jo8f0UU7x6z6_UfwZNQX7FK72E_KfkKOh7R1g@z> (raw)
In-Reply-To: <20190319071256.26302-1-xiaolong.ye@intel.com>

Try to check if external mempool (from rx_queue_setup) is fit for
af_xdp, if it is, it will be registered to af_xdp socket directly and
there will be no packet data copy on Rx and Tx.
