Subject: [PATCH v2 1/5] net/fm10k: remove limit of fm10k_xmit_pkts_vec burst size
Date: Fri,  3 Mar 2017 19:17:27 +0800	[thread overview]
Message-ID: <1488539851-71009-2-git-send-email-zhiyong.yang@intel.com> (raw)
In-Reply-To: <1488539851-71009-1-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.
