Subject: [dpdk-dev] [PATCH 1/5] net/fm10k: remove limit of fm10k_xmit_pkts_vec burst size
Date: Fri, 24 Feb 2017 16:48:17 +0800 [thread overview]
Message-ID: <1487926101-4637-2-git-send-email-zhiyong.yang@intel.com> (raw)
In-Reply-To: <1487926101-4637-1-git-send-email-zhiyong.yang@intel.com>
To add a wrapper function fm10k_xmit_pkts_vec_simple to remove
the limit of tx burst size. The patch makes fm10k vec function
an best effort to transmit the pkts in the consistent behavior
like fm10k_xmit_pkts does that.
