As the kernel driver does not reset the statistics after exiting testpmd,
the previous statistics being retained the next time testpmd is started.
Call 'ice_dcf_stats_reset' during the initialization of the DCF in
order to clear any statistics that may exist from the last use of the DCF
and to avoid statistics errors.
