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.
