I think it would be useful to selectively reset the specific counter if
needed.
something like below(Just to share my thought in C code)
int
rte_event_dev_xstats_reset(uint8_t dev_id,
enum rte_event_dev_xstats_mode mode/* INT_MAX to specify all xstats on the whole device */
const unsigned int ids /* UINT_MAX to specify all the ids on the specific mode */
Other than above comments, Its looks very good.
