Subject: [dpdk-dev] [PATCH v2 1/2] net/i40e: convert to new Rx offloads API
Date: Tue, 27 Mar 2018 16:31:03 +0800	[thread overview]
Message-ID: <20180327083103.163441-1-yanglong.wu@intel.com> (raw)
In-Reply-To: <20180302082011.62982-1-yanglong.wu@intel.com>

Ethdev Rx offloads API has changed since:
commit cba7f53b717d ("ethdev: introduce Rx queue offloads API")
This commit support the new Rx offloads API.
