2.
Run following command.
 /usr/bin/ovs-vsctl --no-wait set Open_vSwitch . other_config:dpdk-socket-mem=1024,1024
 /usr/bin/ovs-vsctl --no-wait set Open_vSwitch . other_config:dpdk-init=true
 /usr/bin/ovs-vsctl --no-wait set Open_vSwitch . other_config:dpdk-lcore-mask=0x2
 /usr/bin/ovs-vsctl --no-wait set Open_vSwitch . other_config:vhost-iommu-support=true
 /usr/bin/ovs-vsctl --timeout 10 add-br br0 -- set bridge br0 datapath_type=netdev
 /usr/bin/ovs-vsctl --timeout 10 set Open_vSwitch . other_config:max-idle=30000
 /usr/bin/ovs-vsctl --timeout 10 set Open_vSwitch . other_config:pmd-cpu-mask=0xaa00000aa00000
 /usr/bin/ovs-vsctl --timeout 10 add-port br0 dpdk0 -- set Interface dpdk0 type=dpdk options:dpdk-devargs=0000:82:00.0 options:n_rxq=4


Actual results:
