Fuel also supports the ovs dpdk scenario. 

Greg, Michal, Fedor,
How do does Fuel get around this on the LF UCS hardware?

All: 


This is not necessarily related to VPP but rather to OVS/DPDK. 

In OPNFV we found the following problem when using UCS NIC. 

The UCS fabric seems to set a VLAN tag on untagged packets. 


Any thoughts from DPDK and VPP folks would be appreciated.

https://jira.opnfv.org/browse/APEX-333 


It is currently deploying DPDK 16.04 and OVS 2.5.90 

I could not find a user accessible setting to do this that would work. The workaround for now we came up with is to set a flow in OVS to strip the tag. 


https://gerrit.opnfv.org/gerrit/#/c/23315/ 

Another solution is to set the nic to strip the vlan in rte eth code or write a DPDK "app" to set the nic.
