+Queue region configuration
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The Ethernet Controller X710/XL710 supports a feature of queue regions
+configuration for RSS in the PF, so that different traffic classes or
+different packet classification types can be separated to different
+queues in different queue regions. There is an API for configuration
+of queue regions in RSS with a command line. It can parse the parameters
+of the region index, queue number, queue start index, user priority, traffic
+classes and so on. Depending on commands from the command line, it will call
+i40e private APIs and start the process of setting or flushing the queue
+region configuration. As this feature is specific for i40e only private
+APIs are used. These new ``test_pmd`` commands are as shown below. For
+details please refer to :doc:`../testpmd_app_ug/index`.
