Version-Release number of selected component (if applicable): DPDK-18.11 How reproducible: 100% Steps to Reproduce: 1.Prepare 2 vms on Azure with dpdk installed 2.The 1st vm, start testpmd with txonly mode. The 2nd one start testpmd with rx-only mode.And set 1st vm's peer mac address as the 2nd vm's mac address. Conversely, set 2nd vm's peer mac address as the 1st one's mac address. #TX-SIDE #./testpmd -c 0xf -n 1 -w 0002:00:02.0 --vdev=3D"net_vdev_netvsc0,iface=3Deth1,force=3D1" -- --port-topology=3Dcha= ined --nb-cores 1 --forward-mode=3Dtxonly --eth-peer=3D1,00:0d:3a:a1:4b:43 --stats-period 1 #RX-SIDE #./testpmd -c 0xf -n 1 -w 0002:00:02.0 --vdev=3D"net_vdev_netvsc0,iface=3Deth1,force=3D1" -- --port-topology=3Dcha= ined --nb-cores 1 --forward-mode=3Drxonly --eth-peer=3D1,00:0d:3a:a1:41:c7 --stats-period 1 3.Keep testpmd running up to 1 minute,then stop testpmd. 4.Check 2 vms' output Actual results: tx-side ++++++++ Accumulated forward statistics for all ports++++++++++ RX-packets: 0 RX-dropped: 0 RX-total: 0 TX-packets: 340381695 TX-dropped: 241822721 TX-total: 582204416 ++++++++++++++++++++++++++++++++++++++++++++++ rx-side ++++++++ Accumulated forward statistics for all ports++++++ RX-packets: 339493162 RX-dropped: 0 RX-total: 339493162 TX-packets: 0 TX-dropped: 0 TX-total: 0 +++++++++++++++++++++++++++++++++++++++++++++ Expected results: There shouldn't be too many(40%-50%) packets in TX-dropped queue Additional info: The bug occurs in latest DPDK upstream --=20 You are receiving this mail because: You are the assignee for the bug.=
