+BNX2X Poll Mode Driver
+======================
+
+The BNX2X poll mode driver library (**librte_pmd_bnx2x**) implements support
+for **QLogic 578xx** 10/20 Gbps family of adapters as well as their virtual
+functions (VF) in SR-IOV context. It is supported on several standard Linux
+distros like Red Hat 7.x and SLES12 OS. It is compile-tested under FreeBSD OS.
+
+More information can be found at `QLogic Corporation's Official Website
+<http://www.qlogic.com>`_.
+
+Supported Features
+------------------
+
+BNX2X PMD has support for:
+
+- Base L2 features
+- Unicast/multicast filtering
+- Promiscuous mode
+- Port hardware statistics
+- SR-IOV VF
+
+Non-supported Features
+----------------------
+
+The features not yet supported include:
+
+- TSS (Transmit Side Scaling)
+- RSS (Receive Side Scaling)
+- LRO/TSO offload
+- Checksum offload
+- SR-IOV PF
+- Rx TX scatter gather
+
+Co-existence considerations
+---------------------------
+
+- BCM578xx being a CNA can have both NIC and Storage personalities.
+  However, coexistence with storage protocol drivers (cnic, bnx2fc and
+  bnx2fi) is not supported on the same adapter. So storage personality
+  has to be disabled on that adapter when used in DPDK applications.
+
+- For SR-IOV case, bnx2x PMD will be used to bind to SR-IOV VF device and
+  Linux native kernel driver (bnx2x) will be attached to SR-IOV PF.
+
+
+Supported QLogic NICs
+---------------------
+
+- 578xx
+
+Prerequisites
+-------------
+
+- Requires firmware version **7.2.51.0**. It is included in most of the
+  standard Linux distros. If it is not available visit
+  `linux-firmware git repository <https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/bnx2x/bnx2x-e2-7.2.51.0.fw>`_
+  to get the required firmware.
+
+Pre-Installation Configuration
+------------------------------
+
+Config File Options
+~~~~~~~~~~~~~~~~~~~
+
+The following options can be modified in the ``.config`` file. Please note that
+enabling debugging options may affect system performance.
+
+- ``CONFIG_RTE_LIBRTE_BNX2X_PMD`` (default **n**)
+
+  Toggle compilation of bnx2x driver. To use bnx2x PMD set this config parameter
+  to 'y'. Also, in order for firmware binary to load user will need zlib devel
+  package installed.
+
+- ``CONFIG_RTE_LIBRTE_BNX2X_DEBUG_TX`` (default **n**)
+
+  Toggle display of transmit fast path run-time messages.
+
+- ``CONFIG_RTE_LIBRTE_BNX2X_DEBUG_RX`` (default **n**)
+
+  Toggle display of receive fast path run-time messages.
+
+- ``CONFIG_RTE_LIBRTE_BNX2X_DEBUG_PERIODIC`` (default **n**)
+
+  Toggle display of register reads and writes.

+Refer to the document :ref:`compiling and testing a PMD for a NIC <pmd_build_and_test>`
+for details.
+
+SR-IOV: Prerequisites and sample Application Notes
+--------------------------------------------------
+
+This section provides instructions to configure SR-IOV with Linux OS.
+
+#. Verify SR-IOV and ARI capabilities are enabled on the adapter using ``lspci``:
+
+   .. code-block:: console
+
+      lspci -s <slot> -vvv
+
+   Example output:
+
+   .. code-block:: console
+
+      [...]
+      Capabilities: [1b8 v1] Alternative Routing-ID Interpretation (ARI)
+      [...]
+      Capabilities: [1c0 v1] Single Root I/O Virtualization (SR-IOV)
+      [...]
+      Kernel driver in use: igb_uio
+
+#. Load the kernel module:
+
+   .. code-block:: console
+
+      modprobe bnx2x
+
+   Example output:
+
+   .. code-block:: console
+
+      systemd-udevd[4848]: renamed network interface eth0 to ens5f0
+      systemd-udevd[4848]: renamed network interface eth1 to ens5f1
+
+#. Bring up the PF ports:
+
+   .. code-block:: console
+
+      ifconfig ens5f0 up
+      ifconfig ens5f1 up
+
+#. Create VF device(s):
+
+   Echo the number of VFs to be created into "sriov_numvfs" sysfs entry
+   of the parent PF.
+
+   Example output:
+
+   .. code-block:: console
+
+      echo 2 > /sys/devices/pci0000:00/0000:00:03.0/0000:81:00.0/sriov_numvfs
+
+#. Assign VF MAC address:
+
+   Assign MAC address to the VF using iproute2 utility. The syntax is:
+   ip link set <PF iface> vf <VF id> mac <macaddr>
+
+   Example output:
+
+   .. code-block:: console
+
+      ip link set ens5f0 vf 0 mac 52:54:00:2f:9d:e8
+
+#. PCI Passthrough:
+
+   The VF devices may be passed through to the guest VM using virt-manager or
+   virsh etc. bnx2x PMD should be used to bind the VF devices in the guest VM
+   using the instructions outlined in the Application notes below.
+
+#. Running testpmd:
+   (Supply ``--log-level="pmd.net.bnx2x.driver",7`` to view informational messages):
+
+   Follow instructions available in the document
+   :ref:`compiling and testing a PMD for a NIC <pmd_build_and_test>`
+   to run testpmd.
+
+   Example output:
+
+   .. code-block:: console
