+=============================================================
+VF L3 forwarding kernel PF test in LPM mode with IPV6 packets
+=============================================================
+
+This document provides benchmark test for NIC VFs which are created from
+kernel PFs or. These tests use l3fwd as a simple forwarder between NIC vfs.
+The goal of this test plan is to have a tested benchmark between NIC vfs.
+The Layer-3 Forwarding  performance results are produced using ``l3fwd`` application.
+For detail test plan, please refer to ``l3fwd_test_plan.rst``.
+
+Prerequisites
+=============
+
+Topology
+--------
+It requires at least 1 port connected traffic generator::
+        Port0 --- TG0
+
+2 ports::
+        Port0 --- TG0
+        Port1 --- TG1
+
+4 ports::
+        Port0 --- TG0
+        Port1 --- TG1
+        Port2 --- TG2
+        Port3 --- TG3
+
+Hardware
+--------
+This suite focus on l3fwd application, so any standard Ethernet Network Adapter is qualified.
+
+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 lpm mode and ipv6, in the case,
+we will send the bi-direction flows with line rate, then we can check the passthrough rate.
+
+The l3fwd application has a number of command line options, here list the key options will be tested::
+
+    ./dpdk-l3fwd [EAL options] -- -p PORTMASK
+                             [--force-max-simd-bitwidth=max-simd-bitwidth]
+                             --config(port,queue,lcore)[,(port,queue,lcore)]
+                             [--rx-queue-size NPKTS]
+                             [--tx-queue-size NPKTS]
+                             [--parse-ptype]
+                             [-L]|[-E]
+                             ...
+    Note:
+        --force-max-simd-bitwidth: This setting is used to determine the vector path for component selection.
+                                   And the default is avx2.
+        --rx-queue-size: Rx queue size in decimal and default is 1024.
+        --tx-queue-size: Tx queue size in decimal and default is 1024.
+        --parse-ptype: Optional, set to use software to analyze packet type.
+                       Without this option, hardware will check the packet type.
+        [-L]|[-E]: L3fwd uses the parameters "-L" and "-E" to correspond to LPM and EM modes respectively.
+                   And the default is LPM mode.
+
+Common Steps
+------------
+1. Bind PF ports to kernel driver, i40e or ice, then create 1 VF from each PF,
+   take E810 for example::
+
+    <dpdk_dir>#echo 1 > /sys/bus/pci/devices/0000\:17\:00.0/sriov_numvfs
+
+   Set vf mac address::
+
+    <dpdk_dir>#ip link set ens5f0 vf 0 mac 00:12:34:56:78:01
+
+   Bind all the created VFs to vfio-pci::
+
+    <dpdk_dir>#./usertools/dpdk-devbind.py -s
+    0000:17:00.0 'Device 1592' if=ens5f0 drv=ice unused=vfio-pci
+    0000:17:01.0 'Device 1592' if=ens5f0v0 drv=iavf 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
+
+2. Configure traffic generator to send traffic
+
+    Routing table for IPv6 packets
+        - In LPM mode, the LPM table used for packet routing is:
+
+        +-------+--------------------------------------------+
+        |   #   |           LPM prefix (IP/length)           |
+        +=======+============================================+
+        |   0   | 2001:0200:0000:0000:0000:0000:0000:0000/64 |
+        +-------+--------------------------------------------+
+        |   1   | 2001:0200:0000:0001:0000:0000:0000:0000/64 |
+        +-------+--------------------------------------------+
+        |   2   | 2001:0200:0000:0002:0000:0000:0000:0000/64 |
+        +-------+--------------------------------------------+
+        |   3   | 2001:0200:0000:0003:0000:0000:0000:0000/64 |
+        +-------+--------------------------------------------+
+
+    The flows need to be configured and started by the traffic generator:
+        - IPv6 packets
+
+        +------+---------+-----------------------------------------+---------+
+        | Flow | Traffic |                                         | IPv6    |
+        |      | Gen.    |           IPV6 Dst. Address             | Src.    |
+        |      | Port    |                                         | Address |
+        +======+=========+=========================================+=========+
+        |   1  |   TG0   | 2001:0200:0000:0000:0000:0000:0000:0000 |  Any Ip |
+        +------+---------+-----------------------------------------+---------+
+        |   2  |   TG1   | 2001:0200:0000:0001:0000:0000:0000:0000 |  Any Ip |
+        +------+---------+-----------------------------------------+---------+
+        |   3  |   TG2   | 2001:0200:0000:0002:0000:0000:0000:0000 |  Any Ip |
+        +------+---------+-----------------------------------------+---------+
+        |   4  |   TG3   | 2001:0200:0000:0003:0000:0000:0000:0000 |  Any Ip |
+        +------+---------+-----------------------------------------+---------+
+
+        Set the packet length : 66 bytes-1518 bytes
+        The IPV6 Src Address increase with the num 1024.
+
+3. Test result table
+
+    +-----------+------------+-------------+---------+
+    |  Fwd_core | Frame Size |  Throughput |   Rate  |
+    +===========+============+=============+=========+
+    |  1C/1T    |    66      |  xxxxx Mpps |   xxx % |
+    +-----------+------------+-------------+---------+
+    |  1C/1T    |   ...      |  xxxxx Mpps |   xxx % |
+    +-----------+------------+-------------+---------+
+    |  2C/2T    |    66      |  xxxxx Mpps |   xxx % |
+    +-----------+------------+-------------+---------+
+    |  2C/2T    |    ...     |  xxxxx Mpps |   xxx % |
+    +-----------+------------+-------------+---------+
+    |  4C/4T    |    66      |  xxxxx Mpps |   xxx % |
+    +-----------+------------+-------------+---------+
+    |  4C/4T    |    ...     |  xxxxx Mpps |   xxx % |
+    +-----------+------------+-------------+---------+
+    |  8C/8T    |    66      |  xxxxx Mpps |   xxx % |
+    +-----------+------------+-------------+---------+
+    |  8C/8T    |    ...     |  xxxxx Mpps |   xxx % |
+    +-----------+------------+-------------+---------+
+
+
+Test Case: test_perf_vf_throughput_ipv6_lpm
+-------------------------------------------
+
+1. Bind VF ports to dpdk driver as common step 1.
+
+2. Launch l3fwd::
+
+     <build_dir>/examples/dpdk-l3fwd -l 5-8 -n 8 --force-max-simd-bitwidth=512 \
+     -- -p 0x1 --config "(0,0,5),(0,1,6),(0,2,7),(0,3,8)" --rx-queue-size 1024 \
+     --tx-queue-size 1024 --parse-ptype
+
+3. Configure traffic generator to send traffic as common step 2.
+
+4. Record Test results as common step 3.
