From: Hideyuki Yamashita <yamashita.hideyuki@po.ntt-tx.co.jp>

This patch is to add another simple usecase of spp_mirror
because current one is too complex to understand how to
use as noted in [1].

+
+Mirroring Packets from NIC
+==========================
+
+This usecase uses two hosts. ``spp_mirror`` is running on localhost. Remote host
+sends ARP packets to localhost by using ping command. ``spp_mirror`` duplicates
+and sends packets to destination ports.
+
+Network Configuration
+---------------------
+
+Detailed configuration is described in
+:numref:`figure_spp_mirror_use_cases_nw_config`.
+In this diagram, incoming packets from ``phy:0`` are mirrored.
+In ``spp_mirror`` process, worker thread ``mir1`` copies incoming packets and
+sends to two destinations ``phy:1`` and ``phy:2``.
+
+.. _figure_spp_mirror_use_cases_nw_config:
+
+.. figure:: ../../images/spp_vf/basic_usecase_mirror_nwconfig.*
+     :width: 80%
+
+     Network configuration of mirroring
+
+
+Setup SPP
+---------
+
+Change directory to spp and confirm that it is already compiled.
+
+.. code-block:: console
+
+    $ cd /path/to/spp
+
+Launch ``spp-ctl`` before launching SPP primary and secondary processes.
+You also need to launch ``spp.py``  if you use ``spp_mirror`` from CLI.
+``-b`` option is for binding IP address to communicate other SPP processes,
+but no need to give it explicitly if ``127.0.0.1`` or ``localhost`` .
+
+.. code-block:: console
+
+    # terminal#1
+    # Launch spp-ctl
+    $ python3 ./src/spp-ctl/spp-ctl -b 192.168.1.100
+
+.. code-block:: console
+
+    # terminal#2
+    # Launch SPP CLI
+    $ python ./src/spp.py -b 192.168.1.100
+
+Start ``spp_primary`` with core list option ``-l 1``.
+
+.. code-block:: console
+
+   # terminal#3
+   $ sudo ./src/primary/x86_64-native-linuxapp-gcc/spp_primary \
+       -l 1 -n 4 \
+       --socket-mem 512,512 \
+       --huge-dir=/run/hugepages/kvm \
+       --proc-type=primary \
+       -- \
+       -p 0x07 -n 10 -s 192.168.1.100:5555
+
+
+Launch spp_mirror
+~~~~~~~~~~~~~~~~~
+
+Run secondary process ``spp_mirror``.
+
+.. code-block:: console
+
+    # terminal#4
+    $ sudo ./src/mirror/x86_64-native-linuxapp-gcc/app/spp_mirror \
+     -l 0,2 -n 4 --proc-type=secondary \
+     -- \
+     --client-id 1 \
+     -s 192.168.1.100:6666 \
+
+Start mirror component with ``CORE_ID`` 2.
+
+.. code-block:: console
+
+    # Start component on CORE_ID 2
+    spp > mirror 1; component start mir1 2 mirror
+
+Add ``phy:0`` as rx ports and add ``phy:1`` and ``phy:2`` as tx port
+to mirror.
+
+.. code-block:: none
+
+   # add ports to mir1
+   spp > mirror 1; port add phy:0 rx mir1
+   spp > mirror 1; port add phy:1 tx mir1
+   spp > mirror 1; port add phy:2 tx mir1
+
+
+Confirm Original Packet is Duplicated
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To check sent packets are mirrored, you run tcpdump for ``ens1`` and ``ens2``
+first. As you run ping for ``ens0``, you will see the same ARP requests trying
+to resolve ``192.168.140.21`` on terminal 1 and 2.
+
+.. code-block:: console
+
+   # terminal#1 at host1
+   # capture on ens1
+   $ sudo tcpdump -i ens1
+    tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
+    listening on ens1, link-type EN10MB (Ethernet), capture size 262144 bytes
+    21:18:44.183261 ARP, Request who-has 192.168.140.21 tell R740n15, length 28
+    21:18:45.202182 ARP, Request who-has 192.168.140.21 tell R740n15, length 28
+    ...
+
+.. code-block:: console
+
+   # terminal#2 at host1
+   # capture on ens2
+   $ sudo tcpdump -i ens2
+    tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
+    listening on ens2, link-type EN10MB (Ethernet), capture size 262144 bytes
+    21:18:44.183261 ARP, Request who-has 192.168.140.21 tell R740n15, length 28
+    21:18:45.202182 ARP, Request who-has 192.168.140.21 tell R740n15, length 28
+    ...
+
+Start to send ARP request with ping.
+
+.. code-block:: console
+
+   # terminal#3 at host1
+   # send packet from NIC0
+   $ ping 192.168.140.21 -I ens0
+
+
+Stop Mirroring
+~~~~~~~~~~~~~~
+
+Delete ports for components.
+
+.. code-block:: none
+
+   # Delete port for mir1
+   spp > mirror 1; port del phy:0 rx mir1
+   spp > mirror 1; port del phy:1 tx mir1
+   spp > mirror 1; port del phy:2 tx mir1
+
+Next, stop components.
+
+.. code-block:: console
+
+   # Stop mirror
+   spp > mirror 1; component stop mir1 2 mirror
+
+   spp > mirror 1; status
+   Basic Information:
+     - client-id: 1
+     - ports: [phy:0, phy:1]
+   Components:
+     - core:2 '' (type: unuse)
+
+Finally, terminate ``spp_mirror`` to finish this usecase.
+
+.. code-block:: console
+
+    spp > mirror 1; exit
