i see same problem with testpmd from dpdk-stable-16.11.9 and if you see below RX-errors counter is getting incremented. dpdk-stable-16.11.9# ./build/build/app/test-pmd/testpmd -w 0000:0b:00.0 -w 0000:13:00.0 -c 0x3 -n 2 --socket-mem 64 -- --burst=64 -i --total-num-mbufs=8192 --port-topology=chained --enable-scatter --enable-lro --mbuf-size=2048 --max-pkt-len=9600 EAL: Detected 4 lcore(s) EAL: No free hugepages reported in hugepages-1048576kB EAL: Debug logs available - lower performance EAL: Probing VFIO support...
