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)
