Hi ,
 
Sorry for confusing you. I will explain my issue clearly.
 
We have installed OVS and DPDK on Ubuntu14.04. We have done our configuration using Physical NIC and Virtual 
Functions (SR-IOV produced Interfaces).
 
We have followed this link: https://software.intel.com/en-us/articles/using-open-vswitch-with-dpdk-for-inter-vm-nfv-applications
 
We are unable to add dpdk on top of OVS bridge.

Hi,I beg a pardon but I'm not entirely clear what you mean with "... mount the Intel 10gig ..."Anyway what I've seen most often is that people struggle with some core parts of the setup and then get refused by OVS trying to add the DPDK port.What you report "...we are not able to add dpdk0 port to ovs bridge..." sounds very similar.
In the past all questions I got only needed to check logs, identify the issue in base ovs+dpdk setup and then things started to work for them.Please take a look at http://askubuntu.com/questions/786510/using-openvswitch-with-dpdk-in-ubuntu-16-04/789203#789203
If it helps you please give it an upvote and let me know.I might consider adding this as a troubleshooting section to the serverguide if this really is a common case.

Hi Christian,
Thanks for writing us.

Hi,The TL;DR is that in Ubuntu 16.04 the base openvswitch-switch package knows nothing about dpdk.But the openvswitch-switch-dpdk package does.
please follow the whole page around https://help.ubuntu.com/16.04/serverguide/DPDK.html#dpdk-openvswitch for some guidance.

Hi Team,

 

We have used ovs+dpdk installed and trying to test with Brocade Vyatta VNF which is  DPDK Supported. We were not able to add dpdk0 port to OVS Bridge.
