     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.
