These are the links to Timers documentation. https://doc.dpdk.org/api/rte__timer_8h.html https://doc.dpdk.org/guides/prog_guide/timer_lib.html
As per my understanding of the documentation, PENDING means timer is scheduled to run but not started.(in a list) RUNNING means timer is presently running. STOPPED means timer has stopped and callback processed. rte_timer_stop() can be used from callbacks for stopping the timer even in case of periodical(multishot timers) my use case is for a single shot , where i have to stop the timer in middle.
