If no 56port mask is specified stats are printed for all DPDK ports. 57 58**--xstats** 59The xstats parameter controls the printing of extended port statistics. If no 60port mask is specified xstats are printed for all DPDK ports. 61 62**--stats-reset** 63The stats-reset parameter controls the resetting of generic port statistics. If 64no port mask is specified, the generic stats are reset for all DPDK ports. 65 66**--xstats-reset** 67The xstats-reset parameter controls the resetting of extended port statistics. 68If no port mask is specified xstats are reset for all DPDK ports. 69 70**-m**: Print DPDK memory information. 71
