Apologies for my non-familiarity with the Eventdev and DPDK Timer features.. but
what does a PMD need to "do" to be capable of TIMER_ADAPTER_CAP_PERIODIC?

I see the code change to enable reporting that "sw pmd supports it", but I didn't
find (in rte_eventdev.h[0] or event-timer-adapter docs[1]) what the PMD must
actually "do" to support it?

If a PMD does not have to actually change anything in the implementation, then why does the flag exist at all?
