+
+======================================================
+Benchmark the performance of VF single core forwarding
+======================================================
+
+Prerequisites
+=============
+
+1.  Nic single core performance test requirements:
+
+    1.1) FVL25G: two dual port FVL25G nics, all installed on the same socket,
+                 pick one port per nic.
+    1.2) NNT10G: four 82599 nics, all installed on the same socket,
+                 pick one port per nic.
+    1.3) CVL100G: one CVL100G nics, all installed on the same socket,
+                 pick one port per nic.
+
+2. Software::
+
+    dpdk: git clone http://dpdk.org/git/dpdk
+    scapy: http://www.secdev.org/projects/scapy/
+    dts (next branch): git clone http://dpdk.org/git/tools/dts, 
+                       then "git checkout next" 
+    Trex code: http://trex-tgn.cisco.com/trex/release/v2.84.tar.gz 
+               (to be run in stateless Layer 2 mode, see section in
+                Getting Started Guide for more details)
+    python-prettytable:
+        apt install python-prettytable (for ubuntu os) 
+        or dnf install python-prettytable (for fedora os). 
+
+3. Connect all the selected nic ports to traffic generator(IXIA,TREX,
+   PKTGEN) ports(TG ports)::
+
+    2 TG 25g  ports for FVL25G ports
+    4 TG 10g  ports for 4 NNT10G ports
+    1 TG 100g ports for CVL100G port
+
+Test Case : Vf Single Core Performance Measurement
+==================================================
+
+1. Bind PF ports to kernel driver, i40e/ixgbe/ice, then create 1 VF from each PF,
+   take XXV710 for example::
+
+    echo 1 > /sys/bus/pci/devices/0000\:af\:00.0/sriov_numvfs
+    echo 1 > /sys/bus/pci/devices/0000\:b1\:00.1/sriov_numvfs
+
+2. 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
+
+3. Bind all the created VFs to dpdk driver, vfio-pci or igb_uio::
+
+    ./usertools/dpdk-devbind.py -b vfio-pci af:02.0 b1:02.0
+
+4. Start testpmd::
+
+    ./dpdk-testpmd -l 28,29 -n 4 -- -i --portmask=0x3  --txd=512 --rxd=512 \
+    --txq=2 --rxq=2 --nb-cores=1
+
+    testpmd> set fwd mac
+    testpmd> start
+
+5. Configure traffic generator to send traffic::
+
+    dst mac: peer nic port mac
+    src ip : random
+    dst ip : fixed
+    frame size: 64 byte
+    transmit rate: 100%
+
+6. Result tables.
+
+   +-----------+------------+---------+-------------+---------+---------------------+
+   |  Fwd_core | Frame Size | TXD/RXD |  Throughput |   Rate  | Expected Throughput |
+   +===========+============+=========+=============+=========+=====================+
+   |  1C/1T    |    64      |   512   |  xxxxx Mpps |   xxx % |  xxxxxxx   Mpps     |
+   +-----------+------------+---------+-------------+---------+---------------------+
+   |  1C/1T    |    64      |   2048  |  xxxxx Mpps |   xxx % |  xxxxxxx   Mpps     |
+   +-----------+------------+---------+-------------+---------+---------------------+
+   |  1C/2T    |    64      |   512   |  xxxxx Mpps |   xxx % |  xxxxxxx   Mpps     |
+   +-----------+------------+---------+-------------+---------+---------------------+
+   |  1C/2T    |    64      |   2048  |  xxxxx Mpps |   xxx % |  xxxxxxx   Mpps     |
+   +-----------+------------+---------+-------------+---------+---------------------+
+
+  Check throughput and compare it with the expected value. Case will raise failure 
+  if actual throughputs have more than 1Mpps gap from expected ones.
+
+Note : 
+   The values for the expected throughput may vary due to different platform and OS, 
+   and traffic generator, please correct threshold values accordingly.
