Subject: [dpdk-dev] [PATCH v3 1/5] net/fm10k: remove limit of fm10k_xmit_pkts_vec burst size
Date: Wed, 29 Mar 2017 15:16:12 +0800 [thread overview]
Message-ID: <1490771776-3362-2-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 fm10k vec function an best effort to transmit
pkts in the consistent behavior like fm10k_xmit_pkts does that.
