+Queue region configuration
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The Ethernet Controller X710/XL710 support a feature of queue regions
+configuration for RSS in 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 region in rss with
+command line. It can parse the parameters of region index, queue number, queue
+start index, user priority, traffic classes and so on. According to commands
+from command line, it will call i40e private API and start the process of set
+or flush queue region configuration. As this feature is specific for i40e, so
+private API is used. These new commands are as below, for details please
reference to
+document testpmd_funcs.rst.
