+DPDK packet capture libraries and tools
+=======================================
 
 This document describes how the Data Plane Development Kit (DPDK) Packet
 Capture Framework is used for capturing packets on DPDK ports. It is intended
 for users of DPDK who want to know more about the Packet Capture feature and
 for those who want to monitor traffic on DPDK-controlled devices.
 
-The DPDK packet capture framework was introduced in DPDK v16.07. The DPDK
-packet capture framework consists of the DPDK pdump library and DPDK pdump
-tool.

+The DPDK packet capture framework was introduced in DPDK v16.07 and
+enhanced in 21.1. The DPDK packet capture framework consists of the
+libraries for collecting packets ``librte_pdump`` and writing packets
+to a file ``librte_pcapng``. There are two sample applications:
+``dpdk-dumpcap`` and older ``dpdk-pdump``.

-The :ref:`dpdk-pdump <pdump_tool>` tool is developed based on the
-``librte_pdump`` library.  It runs as a DPDK secondary process and is capable

+Packet Capture File Writer
+==========================
+
+Pcapng is a library for creating files in Pcapng file format.
+The Pcapng file format is the default capture file format for modern
+network capture processing tools. It can be read by wireshark and tcpdump.
+
+Usage
+-----
+
+Before the library can be used the function ``rte_pcapng_init``
+should be called once to initialize timestamp computation.

+
+dpdk-dumpcap Application
+========================
+
+The ``dpdk-dumpcap`` tool is a Data Plane Development Kit (DPDK)
+network traffic dump tool.  The interface is similar to  the dumpcap tool in Wireshark.
+It runs as a secondary DPDK process and lets you capture packets that are
+coming into and out of a DPDK primary process.
+The ``dpdk-dumpcap`` writes files in Pcapng packet format using
+capture file format is pcapng.
+
+Without any options set it will use DPDK to capture traffic from the first
+available DPDK interface and write the received raw packet data, along
+with timestamps into a pcapng file.
+
+If the ``-w`` option is not specified, ``dpdk-dumpcap`` writes to a newly
+create file with a name chosen based on interface name and timestamp.
+If ``-w`` option is specified, then that file is used.
+
+   .. Note::
+      * The ``dpdk-dumpcap`` tool can only be used in conjunction with a primary
+        application which has the packet capture framework initialized already.
+        In dpdk, only the ``testpmd`` is modified to initialize packet capture
+        framework, other applications remain untouched. So, if the ``dpdk-dumpcap``
+        tool has to be used with any application other than the testpmd, user
+        needs to explicitly modify that application to call packet capture
+        framework initialization code. Refer ``app/test-pmd/testpmd.c``
+        code to see how this is done.
+
+      * The ``dpdk-dumpcap`` tool runs as a DPDK secondary process. It exits when
+        the primary application exits.
+
+
+Running the Application
+-----------------------
+
+To list interfaces available for capture use ``--list-interfaces``.
+
+To filter packets in style of *tshark* use the ``-f`` flag.
+
+To capture on multiple interfaces at once, use multiple ``-I`` flags.
+
+Example
+-------
+
+.. code-block:: console
+
+   # ./<build_dir>/app/dpdk-dumpcap --list-interfaces
+   0. 000:00:03.0
+   1. 000:00:03.1
+
+   # ./<build_dir>/app/dpdk-dumpcap -I 0000:00:03.0 -c 6 -w /tmp/sample.pcapng
+   Packets captured: 6
+   Packets received/dropped on interface '0000:00:03.0' 6/0
+
+   # ./<build_dir>/app/dpdk-dumpcap -f 'tcp port 80'
+   Packets captured: 6
+   Packets received/dropped on interface '0000:00:03.0' 10/8
+
+
+Limitations
+-----------
+The following option of Wireshark ``dumpcap`` is not yet implemented:
+
+   * ``-b|--ring-buffer`` -- more complex file management.
+
+The following options do not make sense in the context of DPDK.
+
+   * ``-C <byte_limit>`` -- its a kernel thing
+
+   * ``-t`` -- use a thread per interface
+
+   * Timestamp type.
+
+   * Link data types. Only EN10MB (Ethernet) is supported.
+
+   * Wireless related options:  ``-I|--monitor-mode`` and  ``-k <freq>``
+
+
+.. Note::
+   * The options to ``dpdk-dumpcap`` are like the Wireshark dumpcap program and
+     are not the same as ``dpdk-pdump`` and other DPDK applications.
