Hi,

To use pcap PMD, user should prepare rx_pcap before launching SPP,
or failed to not found. This update is for creating rx_pcap device
before adding pcap PMD to avoid the error.

It is required to install text2pap, which is included in wireshark,
to create pcap file. 

This update is also including requirements for text2pcap and usecases
for describing the usage of pcap PMD.

Thanks,
Yasufumi

Libpcap-based PMD of DPDK requires two different streams for rx and tx
of pcap files[1]. 'tx_pcap' is created by DPDK but not for 'rx_pcap'.
In SPP, rx pcap file should be prepared like as '/tmp/spp-rx1.pcap'
before 'add pcap', or failed to setup pcap PMD.

This update is for creating the rx pcap with 'text2pcap'[2] if it does
not exist.

This update is also including definition of format of pcap files in
src/shared/common.h as following.

  #define PCAP_IFACE_RX "/tmp/spp-rx%d.pcap"
  #define PCAP_IFACE_TX "/tmp/spp-tx%d.pcap"

+Single spp_nfv with PCAP PMD
+-----------------------------
+
+PCAP PMD
+~~~~~~~~
+
+Pcap PMD is an interface for capturing or restoring traffic.
+For usign pcap PMD, you should set ``CONFIG_RTE_LIBRTE_PMD_PCAP``
+to ``y`` and compile DPDK before SPP.
+Refer to
+:ref:`Install DPDK and SPP<install_dpdk_spp>`
+for details of setting up.
+
+Pcap PMD has two different streams for rx and tx.
+Tx device is for capturing packets and rx is for restoring captured
+packets.
+For rx device, you can use any of pcap files other than SPP's pcap PMD.
+
+To start using pcap pmd, just using ``add`` subcommand as ring.
+Here is an example for creating pcap PMD with index ``1``.
+
+.. code-block:: console
+
+    spp > sec 1;add pcap 1
+
+After running it, you can find two of pcap files in ``/tmp``.
+
+.. code-block:: console
+
+    $ ls /tmp | grep pcap$
+    spp-rx1.pcap
+    spp-tx1.pcap
+
+If you already have a dumped file, you can use it by it putting as
+``/tmp/spp-rx1.pcap`` before running the ``add`` subcommand.
+SPP does not overwrite rx pcap file if it already exist,
+and it just overwrites tx pcap file.
+
+Capture Incoming Packets
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+As the first usecase, add a pcap PMD and capture incoming packets from
+``phy:0``.
+
+.. code-block:: console
+
+    spp > sec 1;add pcap 1
+    spp > sec 1;patch phy:0 pcap:1
+    spp > sec 1;forward
+
+In this example, we use pktgen.
+Once you start forwarding packets from pktgen, you can see
+that the size of ``/tmp/spp-tx1.pcap`` is increased rapidly
+(or gradually, it depends on the rate).
+
+.. code-block:: console
+
+    Pktgen:/> set 0 size 1024
+    Pktgen:/> start 0
+
+To stop capturing, simply stop forwarding of ``spp_nfv``.
+
+.. code-block:: console
+
+    spp > sec 1;stop
+
+You can analyze the dumped pcap file with other tools like as wireshark.
+
+Restore dumped Packets
+~~~~~~~~~~~~~~~~~~~~~~
+
+In this usecase, use dumped file in previsou section.
+Copy ``spp-tx1.pcap`` to ``spp-rx2.pcap`` first.
+
+.. code-block:: console
+
+    $ sudo cp /tmp/spp-tx1.pcap /tmp/spp-rx2.pcap
+
+Then, add pcap PMD to another ``spp_nfv`` with index ``2``.
+
+.. code-block:: console
+
+    spp > sec 2;add pcap 2
+
+You can find that ``spp-tx2.pcap`` is creaeted and ``spp-rx2.pcap``
+still remained.
+
+.. code-block:: console
+
+    $ ls -al /tmp/spp*.pcap
+    -rw-r--r-- 1 root root         24  ...  /tmp/spp-rx1.pcap
+    -rw-r--r-- 1 root root 2936703640  ...  /tmp/spp-rx2.pcap
+    -rw-r--r-- 1 root root 2936703640  ...  /tmp/spp-tx1.pcap
+    -rw-r--r-- 1 root root          0  ...  /tmp/spp-tx2.pcap
+
+To confirm packets are restored, patch ``pcap:2`` to ``phy:1``
+and watch received packets on pktgen.
+
+.. code-block:: console
+
+    spp > sec 2;patch phy:1 pcap:2
+    spp > sec 2;forward
+
+After started forwarding, you can see that packet count is increased.
