+===============================================================
+Benchmark the performance of iavf checksum forwarding with E810
+===============================================================
+
+Description
+===========
+
+Prerequisites
+=============
+
+1. Hardware:
+
+   1.1) vf checksum perf test for Intel® Ethernet Network Adapter E810-CQDA2:
+        1 NIC or 2 NIC cards attached to the same processor and 1 port used of each NIC.
+   1.2) vf checksum perf test for Intel® Ethernet Network Adapter E810-XXVDA4:
+        1 NIC card attached to the processor and 4 ports used.
+
+2. Software::
+
+    dpdk: git clone http://dpdk.org/git/dpdk
+    trex: git clone http://trex-tgn.cisco.com/trex/release/v2.93.tar.gz
+
+
+Test Case
+=========
+The test case check the throughput result with ipv4, in the case,
+we will send the bi-direction flows with line rate, then we can check the
+passthrough rate.
+
+Common Steps
+------------
+1. Bind PF ports to kernel driver(ice), then create 1 VF from each PF,
+   take E810-CQDA2 for example::
+
+    echo 1 > /sys/bus/pci/devices/0000\:17\:00.0/sriov_numvfs
+    echo 1 > /sys/bus/pci/devices/0000\:4b\:00.0/sriov_numvfs
+
+2. Ip link set VF trust on and spoofchk off on DUT::
+
+    ip link set $PF_INTF vf 0 trust on
+    ip link set $PF_INTF vf 0 spoofchk off
+
+3. Set vf mac address::
+
+    ip link set ens5f0 vf 0 mac 00:12:34:56:78:01
+    ip link set ens6f0 vf 0 mac 00:12:34:56:78:02
+
+4. Bind tested ports to vfio-pci::
+
+    <dpdk_dir>#./usertools/dpdk-devbind.py -s
+    0000:17:00.0 'Device 1592' if=ens5f0 drv=ice unused=vfio-pci
+    0000:4b:00.0 'Device 1592' if=ens6f0 drv=ice unused=vfio-pci
+    <dpdk_dir>#./usertools/dpdk-devbind.py -b vfio-pci <pci device id>
+    <dpdk_dir>#./usertools/dpdk-devbind.py -b vfio-pci 0000:17:01.0
+    <dpdk_dir>#./usertools/dpdk-devbind.py -b vfio-pci 0000:4b:01.0
+
+5. Configure traffic generator to send traffic
+
+    Test flow MAC table.
+
+    +------+---------+------------+----------------+
+    | Flow | Traffic | MAC        | MAC            |

+    |   1  |   TG0   | Random MAC | 00:12:34:56:01 |
+    +------+---------+------------+----------------+
+    |   2  |   TG1   | Random Mac | 00:12:34:56:02 |
+    +------+---------+------------+----------------+
+
+    The Flow IP table.
+
+    +------+---------+------------+------------+
+    | Flow | Traffic | IPV4       | IPV4       |
+    |      | Gen.    | Src.       | Dest.      |
+    |      | Port    | Address    | Address    |
+    +======+=========+============+============+
+    |   1  |   TG0   | Any IP     | 198.18.1.0 |
+    +------+---------+------------+------------+
+    |   2  |   TG1   | Any IP     | 198.18.0.0 |
+    +------+---------+------------+------------+
+
+    Set the packet length : 128 bytes-1518 bytes
+    The IPV4 Dest Address increase with the num 1024.
+
+6. Test results table.
+
+    +-----------+------------+-------------+---------+
+    |  Fwd_core | Frame Size |  Throughput |   Rate  |
+    +===========+============+=============+=========+
+    |  1C/1T    |    128     |  xxxxx Mpps |   xxx % |
+    +-----------+------------+-------------+---------+
