+SZEDATA2 poll mode driver library
+=================================
+
+The SZEDATA2 poll mode driver library implements support for cards from COMBO
+family (**COMBO-80G**, **COMBO-100G**).
+The SZEDATA2 PMD is virtual PMD which uses interface provided by libsze2
+library to communicate with COMBO cards over sze2 layer.
+
+More information about family of
+`COMBO cards <https://www.liberouter.org/technologies/cards/>`_
+and used technology
+(`NetCOPE platform <https://www.liberouter.org/technologies/netcope/>`_) can be
+found on the `Liberouter website <https://www.liberouter.org/>`_.
+
+.. note::
+
+ This driver has external dependencies.
+ Therefore it is disabled in default configuration files.
+ It can be enabled by setting ``CONFIG_RTE_LIBRTE_PMD_SZEDATA2=y``
+ and recompiling.
+
+Prerequisities
+--------------
+
+This PMD requires kernel modules which are responsible for initialization and
+allocation of resources needed for sze2 layer function.
+Communication between PMD and kernel modules is mediated by libsze2 library.
+These kernel modules and library are not part of DPDK and must be installed
+separately:
+
+* **libsze2 library**
+
+ The library provides API for initialization of sze2 transfers, receiving and
+ transmitting data segments.
+
+* **Kernel modules**
+
+ * combov3
+ * szedata2_cv3
+
+ Kernel modules manage initialization of hardware, allocation and
+ sharing of resources for user space applications:
+
+Information about getting the dependencies can be found `here
+<https://www.liberouter.org/technologies/netcope/access-to-libsze2-library/>`_.
+
+
+Using the SZEDATA2 PMD
+----------------------
+
+SZEDATA2 PMD can be created by passing ``--vdev=`` option to EAL in the
+following format:
+
+.. code-block:: console
+
+ --vdev 'DEVICE,dev_path=PATH,rx_ifaces=RX_MASK,tx_ifaces=TX_MASK'
+
+``DEVICE`` and options ``dev_path``, ``rx_ifaces``, ``tx_ifaces`` are mandatory
+and must be separated by commas.
+
+* ``DEVICE``: contains prefix ``eth_szedata2`` followed by numbers or letters,
+ must be unique for each virtual device
+
+* ``dev_path``: Defines path to szedata2 device.
+ Value is valid path to szedata2 device. Example:
+
+ .. code-block:: console
+
+ dev_path=/dev/szedataII0
+
+* ``rx_ifaces``: Defines which receive channels will be used.
+ For each channel is created one queue. Value is mask for selecting which
+ receive channels are required. Example:
+
+ .. code-block:: console
+
+ rx_ifaces=0x3
+
+* ``tx_ifaces``: Defines which transmit channels will be used.
+ For each channel is created one queue. Value is mask for selecting which
+ transmit channels are required. Example:
+
+ .. code-block:: console
+
+ tx_ifaces=0x3
+
+Example of usage
+----------------
+
+Read packets from 0. and 1. receive channel and write them to 0. and 1.
+transmit channel:
+
+.. code-block:: console
+
+ $RTE_TARGET/app/testpmd -c 0xf -n 2 \
+ --vdev 'eth_szedata20,dev_path=/dev/szedataII0,rx_ifaces=0x3,tx_ifaces=0x3' \
+ -- --port-topology=chained --rxq=2 --txq=2 --nb-cores=2
