Here is a suggested reworking with minor changes and a link to the testpmd docs:

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`.

.. code-block:: console

   testpmd> set port (port_id) queue-region region_id (value) \
		queue_start_index (value) queue_num (value)
   testpmd> set port (port_id) queue-region region_id (value) flowtype (value)
   testpmd> set port (port_id) queue-region UP (value) region_id (value)
   testpmd> set port (port_id) queue-region flush (on|off)
   testpmd> show port (port_id) queue-region
