assignment in hypervisor. Take qemu for example, the device assignment should carry the IAVF device id (0x1889) like
``-device vfio-pci,x-pci-device-id=0x1889,host=03:0a.0``.
+ When IAVF is backed by an Intel® E810 device, the "Protocol Extraction" feature which is supported by ice PMD is also
+ available for IAVF PMD. The same devargs with the same parameters can be applied to IAVF PMD, for detail please reference
+ the section ``Protocol extraction for per queue`` of ice.rst.

* **Updated Intel iavf driver.**

+ * Added support for flexible descriptor metadata extraction.
* Added support of AVX512 instructions in Rx and Tx path.
