Subject: [dpdk-dev] [PATCH v5 08/10] examples/tep_termination:add TSO offload configuration
Date: Tue, 23 Jun 2015 00:41:03 +0800 [thread overview]
Message-ID: <1434991265-20384-9-git-send-email-jijiang.liu@intel.com> (raw)
In-Reply-To: <1434991265-20384-1-git-send-email-jijiang.liu@intel.com>
Add the tso-segsz option for TSO offload.
If the 'tso-segsz' is not 0, it means TSO offload is enabled.
Signed-off-by: Jijiang Liu <jijiang.liu@intel.com>
