Intel Virtual Function Driver
=============================
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.
+Intel products starting Ethernet Controller 700 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.
* `Intel® AVF HAS <https://www.intel.com/content/dam/www/public/us/en/documents/product-specifications/ethernet-adaptive-virtual-function-hardware-spec.pdf>`_
+.. note::
+
+ To use DPDK AVF PMD on Intel® 700 Series Ethernet Controller, the device id (0x1889) need to specified during device
+ assignment in hypervisor. Take qemu for example, the device assignment should carry the AVF device id (0x1889) like
+ ``-device vfio-pci,x-pci-device-id=0x1889,host=03:0a.0``.

+#. If use vfio-pci to pass through device instead of pci-assign, steps 8 and 9 need to be updated to bind device to vfio-pci and
+ replace pci-assign with vfio-pci when start virtual machine.
