Subject: [dpdk-dev] [PATCH v3 2/5] net/i40e: remove limit of i40e_xmit_pkts_vec burst size
Date: Wed, 29 Mar 2017 15:16:13 +0800 [thread overview]
Message-ID: <1490771776-3362-3-git-send-email-zhiyong.yang@intel.com> (raw)
In-Reply-To: <1490771776-3362-1-git-send-email-zhiyong.yang@intel.com>
To add a wrapper function to remove the limit of tx burst size. The patch
makes i40e vec function an best effort to transmit the pkts in the
consistent behavior like i40e_xmit_pkts_simple and i40e_xmit_pkts do that.
