+
+======================================================================
+Benchmark the performance of single core forwarding with FVL25G/NNT10G
+======================================================================
+
+Prerequisites
+=============
+
+1. Hardware:
+ 1) nic_single_core_perf test for FVL25G: two dual port FVL25G nics,
+ all installed on the same socket, pick one port per nic
+ 3) nic_single_core_perf test for NNT10G : four 82599 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/v2.26.tar.gz
+ 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
+
+Test Case : Single Core Performance Measurement
+===============================================
+1) Bind tested ports to igb_uio
+
+2) Start testpmd::
+
+ ./x86_64-native-linuxapp-gcc/app/testpmd -c 0x6 -n 4 -- -i \
+ --portmask=0xf --txd=128 --rxd=128
+ testpmd> start
+
+3) Configure traffic generator to send traffic
+ configure one below stream for each TG port
+ dst mac: peer nic port mac
+ src ip : random
+ dst ip : random
+ packet length : 64 byte
+
+4) check throughput and compare it with the expected value.
+
+5) for NNT10G, repeat above step 1-4 for txd=rxd=512,2048 separately.
+ for FVL25G nic, just test txd=rxd=512,2048 following above steps
+ 1-4.
+
+6) Result tables for different NICs:
+
+ FVL25G:
++------------+---------+-------------+---------+---------------------+
+| Frame Size | TXD/RXD | Throughput | Rate | Expected Throughput |
++------------+---------+-------------+---------+---------------------+
+| 64 | 512 | xxxxxx Mpps | xxx % | xxx Mpps |
+| 64 | 2048 | xxxxxx Mpps | xxx % | xxx Mpps |
++------------+---------+-------------+---------+---------------------+
+
+ for NNT10G:
++------------+---------+-------------+---------+---------------------+
+| Frame Size | TXD/RXD | Throughput | Rate | Expected Throughput |
++------------+---------+-------------+---------+---------------------+
+| 64 | 128 | xxxxxx Mpps | xxx % | xxx Mpps |
+| 64 | 512 | xxxxxx Mpps | xxx % | xxx Mpps |
+| 64 | 2048 | xxxxxx Mpps | xxx % | xxx Mpps |
++------------+---------+-------------+---------+---------------------+
+
+Note : The values for the expected throughput may vary due to different
+ platform and OS, and traffic generator, please correct threshold
+ values accordingly. (the above expected values for FVL 25G and
+ NNT10G were got from the combination of Purly,Ubuntu 16.04, and
+ traffic generator IXIA)
+
+Case will raise failure if actual throughputs have more than 1Mpps gap
+from expected ones.

For next branch: add the expected throughput values for NICs:
"niantic"(4 ports), "fortville_25g"(2 ports), and the values
will be parsed by the test suite.

For next branch: conducts single core performace test for NICs:
"niantic"(4 ports required),"fortville_25g"(2 ports required),
the traffic generator is TREX, and there is a flag to determine
if save the test result as a separate file or not.
