3. init openvswitch and add test nic to ovs bridge
ovs-vsctl set Open_vSwitch . other_config={}
ovs-vsctl set Open_vSwitch . other_config:dpdk-socket-mem=4096
ovs-vsctl set Open_vSwitch . other_config:pmd-cpu-mask=550000550000
ovs-vsctl set Open_vSwitch . other_config:dpdk-lcore-mask=0x1
ovs-vsctl set Open_vSwitch . other_config:vhost-iommu-support=true
ovs-vsctl set Open_vSwitch . other_config:userspace-tso-enable=false
ovs-vsctl set Open_vSwitch . other_config:dpdk-init=true

ovs-vsctl --if-exists del-br ovsbr0
ovs-vsctl --may-exist add-br ovsbr0 
ovs-vsctl --if-exists del-port ovsbr0 dpdk0
ovs-vsctl add-port ovsbr0 dpdk0 --  set Interface dpdk0 type=dpdk options:dpdk-devargs=0000:3b:00.0 options:n_rxq=1 options:n_rxq_desc=1024 options:n_txq_desc=1024 mtu_request=9120

Actual results:
on the step3, add dpdk0 port failed.
ovs-vsctl: Error detected while setting up 'dpdk0': Error attaching device '0000:3b:00.0' to DPDK.  See ovs-vswitchd log for details.
ovs-vsctl: The default log directory is "/var/log/openvswitch".


Expected results:
on the step3, add dpdk0 port as well
