+Poll Mode Driver for Emulated Backend of Intel® AVF
+===================================================
+
+Intel® AVF is an Ethernet SR-IOV Virtual Function with the same
+device id (8086:1889) on different Intel Ethernet Controller.
+
+Emulated Backend of Intel® AVF is software emulated device to provide
+IAVF compatible layout and acceleartion to the consumer who is using IAVF.
+The communication is using vfio-user protocol as transport mechanism.
+While, the Backend PMD driver is based on *librte_vfio_user* and *librte_emudev* libraries.
+
+PMD arguments
+-------------
+
+Below devargs are provided to setup iavf_be device in DPDK:
+
+#.  ``emu``:
+
+    The emudev name it depends on.
+    (required)
+
+#.  ``mac``:
+
+    It is the MAC address assigned to it, and Front End device would consider it as its default MAC. If no set, driver would take a random one.
+    (optional)
+
+Set up an iavf_be interface
+---------------------------
+
+The following example will set up an iavf_be interface in DPDK:
+
+.. code-block:: console
+
+    --vdev emu_iavf0,sock=/tmp/to/socket/emu_iavf0,queues=4 --vdev net_iavfbe0,emu=emu_iavf0,mac=00:11:22:33:44:55
+
+Features and Limitations of iavf_be PMD
+---------------------------------------
+Currently, the iavf_be PMD provides the basic functionality of packet reception, transmission and event handling.
+
+*   It has multiple queues support.
+
+*   It supports Base mode virtchnl messages processing.
+
+*   Don't need to stop RX/TX manually, stop guest or iavf driver on guest instead.
+
+*   It is running in Polling mode, no RX interrupt support.
+
+*   No MAC VLAN filtering support.
+
+*   No classification offload support.
