How to use dpdk ovs

How to use dpdk ovs

[topperxin]

Hi all
       I'm freshman of dpdk.
       And , I want to use dpdk ovs. I compiled successfully.
       like:
           Bridge "br0"
                  Port "br0"
                           Interface "br0"
                           type: internal
                  Port "dpdk0"
                           Interface "dpdk0"
                           type: dpdk
        But ,I don't know how to use the dpdk port, how to let the data flow go through the dpdk0?
        Who can tell me, thanks a lot.

Hi,
Below are the seps that I followed to get DPDK with OVS. Some of the 
paths need to be changed to your env..
#12 Test Switching using OpenVSwitch with DPDK **************
#--- Setup the ifaces as dpdk..
cd /home/vnspteam01/dpdk-1.7.1
cd /home/vnspteam01/dpdk-1.8.0
sudo modprobe uio
sudo modprobe cuse
sudo rmmod igb_uio
sudo rmmod rte_kni
sudo insmod x86_64-native-linuxapp-gcc/kmod/igb_uio.ko
#**** Assign the dpdk capable interfaces to igb_uio driver
