>The telemetry library is connected with eventdev xstats and port link info. The

>/eventdev/dev_list
>/eventdev/port_list,DevID
>/eventdev/queue_list,DevID
>/eventdev/dev_xstats,DevID
>/eventdev/port_xstats,DevID,PortID
>/eventdev/queue_xstats,DevID,PortID
>/eventdev/queue_links,DevID,PortID
>
>queue_links command displays a list of queues linked with a specified
>eventdev port and a service priority associated with each link.
