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.

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