+=======================================================================================
+Benchmark the performance of pf multi driver forwarding with Intel® Ethernet 700 Series
+=======================================================================================
+
+Description
+===========
+
+The feature reduce the ITR interval of multi-driver mode in driver i40e.
+Set the multi-driver mode in driver i40e, the perf will no drop compare with
+no multi-driver mode.
+
+Prerequisites
+=============
+
+1. Hardware::
+
+   I40e: XXV710, XL710, X710
+
+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 tested ports to vfio-pci::
+
+    <dpdk_dir>#./usertools/dpdk-devbind.py -s
+    0000:b1:00.0 'Ethernet Controller XXV710 for 25GbE SFP28 158b' if=ens21f0 drv=i40e unused=vfio-pci
+    0000:ca:00.0 'Ethernet Controller XXV710 for 25GbE SFP28 158b' if=ens25f0 drv=i40e 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:b1:00.0
+    <dpdk_dir>#./usertools/dpdk-devbind.py -b vfio-pci 0000:ca:00.0
+
+2. Configure traffic generator to send traffic
+
+    Test flow MAC table.
+
+    +------+---------+------------+----------------+
+    | Flow | Traffic | MAC        | MAC            |
+    |      | Gen.    | Src.       | Dst.           |
+    |      | Port    | Address    | Address        |
+    +======+=========+============+================+
+    |   1  |   TG0   | Random MAC | 11:22:33:44:55 |
+    +------+---------+------------+----------------+
+    |   2  |   TG1   | Random Mac | 11:22:33:44:55 |
+    +------+---------+------------+----------------+
+
+    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 : 64 bytes-1518 bytes
+    The IPV4 Dest Address increase with the num 1024.
+
+3. Test results table.
+
+    +-----------+------------+-------------+---------+
+    |  Fwd_core | Frame Size |  Throughput |   Rate  |
+    +===========+============+=============+=========+
+    |  1C/1T    |    64      |  xxxxx Mpps |   xxx % |
+    +-----------+------------+-------------+---------+
+    |  1C/1T    |   ...      |  xxxxx Mpps |   xxx % |
+    +-----------+------------+-------------+---------+
+
+Test Case 1: test_perf_enable_multi_driver
+------------------------------------------
+test steps
+~~~~~~~~~~
+1. Bind PF ports to dpdk driver as common step 1::
+
+    ./usertools/dpdk-devbind.py -b vfio-pci b1:00.0 ca:00.0
+
+2. Start dpdk-testpmd with multi driver::
+
+     <build_dir>/app/dpdk-testpmd -l 5,6 -n 8 --force-max-simd-bitwidth=512 \
+     -a 0000:b1:00.0,support-multi-driver=1 -a 0000:ca:00.0,support-multi-driver=1 \
+     -- -i --portmask=0x3 --rxq=1 --txq=1 --txd=1024 --rxd=1024 --forward=io \
+     --nb-cores=1
+
+    Note:
+      -force-max-simd-bitwidth: set 512.
+      support-multi-driver: enable multi driver
+
+3. Configure traffic generator to send traffic as common step 2.
+
+4. Record Test results as common step 3.
