+Intel® Ethernet Adaptive Virtual Function
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Adaptive Virtual Function (AVF) is a SR-IOV Virtual Function with the same device id (8086:1889) on different Intel Ethernet Controller.
+AVF Driver is VF driver which supports for all future Intel devices without requiring a VM update. And since this happens to be an adaptive VF driver,
+every new drop of the VF driver would add more and more advanced features that can be turned on in the VM if the underlying HW device supports those
+advanced features based on a device agnostic way without ever compromising on the base functionality. AVF provides generic hardware interface and
+interface between AVF driver and a compliant PF driver is specified.
+
+Intel products starting Ethernet Controller 710 Series to support Adaptive Virtual Function.
+
+The way to generate Virtual Function is like normal, and the resource of VF assignment depends on the NIC Infrastructure.
