Subject: [dpdk-dev] [PATCH v6 9/9] app/testpmd:test VxLAN Tx checksum offload
Date: Tue, 21 Oct 2014 16:46:08 +0800 [thread overview]
Message-ID: <1413881168-20239-10-git-send-email-jijiang.liu@intel.com> (raw)
In-Reply-To: <1413881168-20239-1-git-send-email-jijiang.liu@intel.com>
Add test cases in testpmd to test VxLAN Tx Checksum offload, which include
- IPv4 and IPv6 packet
- outer L3, inner L3 and L4 checksum offload for Tx side.
