Is this should be "info" level or debug, is end user interested if timer
expired or not?

btw, what is the logic in pmd, when to use PMD_DRV_LOG and when to use
PMD_DEBUG_LOG?

Extra line.

The  PMD_DRV_LOG macro is a local wrapper on RTE_LOG, while the
PMD_DEBUG_LOG macro is a compile-time conditional macro to the same
RTE_LOG.  The DEBUG_LOG macro is conditionalize on the configuration
RTE_LIBRTE_ARK_DEBUG_TRACE.
