A= dditionally I used the ethregs tool and confirmed that the registers are in= deed 0. Is this expected behavior, and is there a proper way to get per que= ue packet counts from hardware registers? >=20 > ./dpdk-testpmd -l 0-8 -n 4 -m5120,5120 -- -i --forward-mode=3Drxonly --r= xq=3D2 --txq=3D2 --portmask=3D0xc --rxd=3D65536 --nb-cores=3D8 --rss-ip >=20 Are you sending packets with different IP addresses?
