Sorry for forgetting to include mail list, I'm re-sending my reply.
The problem is that there isn't dpdk0 or dpdk1 port shown up.
So I can't add dpdk port to the brige, which means that I can't use dpdk to
transfer packets.
I didn't add any other ports to the brige, because I intend to use OVS-DPDK.
The result of dpdk-devbind.py --status:
Network devices using DPDK-compatible driver

0000:8b:00.0 '82599ES 10-Gigabit SFI/SFP+ Network Connection' drv=vfio-pci

drv=ixgbe unused=vfio-pci
Since there isn't any dpdk port, I try to add the 10G Ethernet NIC(its name
is ens5f0) to the bridge, then get this:
# ovs-vsctl add-port ovsbr ens5f0
ovs-vsctl: Error detected while setting up 'ens5f0'. See ovs-vswitchd log
for details.
Log detail is:
2016-10-26T12:53:01.806Z|00047|bridge|WARN|could not open network device
ens5f0 (No such device).
The result of ovs-vsctl show:
