The problem appears to be with the Netronome PMD as the get_stats call just calls in to the PMD to get the stats. I would look in the PMD and see if they support stats gathering. Should be a table in the driver to tell ethdev which function to call. This really is not a Pktgen problem, but a DPDK/Netronome PMD problem.
