i have a X520-SR2 10G Network Card, i gonna use that to create 2 virtual interfaces with OpenvSwitch that compiled with dpdk (installed from repository of ubuntu 18.04) and test this virtual interfaces with testpmd, i do following jobs :
Create Bridge
$ ovs-vsctl add-br br0 -- set bridge br0 datapath_type=netdev bind dpdk ports
$ ovs-vsctl add-port br0 dpdk0 -- set Interface dpdk0 type=dpdk options:dpdk-devargs=0000:01:00.0 ofport_request=1 $ ovs-vsctl add-port br0 dpdk1 -- set Interface dpdk1 type=dpdk options:dpdk-devargs=0000:01:00.1 ofport_request=2 create dpdkvhostuser ports
$ ovs-vsctl add-port br0 dpdkvhostuser0 -- set Interface dpdkvhostuser0 type=dpdkvhostuser ofport_request=3 $ ovs-vsctl add-port br0 dpdkvhostuser1 -- set Interface dpdkvhostuser1 type=dpdkvhostuser ofport_request=4 define flow directions
# clear all directions $ ovs-ofctl del-flows br0 Add new flow directions
$ ovs-ofctl add-flow br0 in_port=3,dl_type=0x800,idle_timeout=0,action=output:4 $ ovs-ofctl add-flow br0 in_port=4,dl_type=0x800,idle_timeout=0,action=output:3 Dump flow directions
$ ovs-ofctl dump-flows br0 cookie=0x0, duration=851.504s, table=0, n_packets=0, n_bytes=0, ip,in_port=dpdkvhostuser0 actions=output:dpdkvhostuser1 cookie=0x0, duration=851.500s, table=0, n_packets=0, n_bytes=0, ip,in_port=dpdkvhostuser1 actions=output:dpdkvhostuser0 now i run testpmd:

what should i do now ?? where is the problem from?
