Customer traffic to a VF on a SRIOV port is QinQ double tagged. 

Traffic is being dropped at the VF interface. Network traffic to VF as single vlanid tagged works as expected

At compute node SRIOV ports

Physical server is HP DL 380 G9, SRIOV physical NIC is Intel x710

Behaviour occurs when sending double tagged traffic for the VF interface

Compute host  SRIOV VF unable to receive QinQ double tagged traffic as expected.

Some more details on our environment:
- Compute node deployed in OSP 10 {not generic KVM in article}
- Compute node  is running RHEL 7  {not RHEL 6 in article}
- Compute nodes are running Intel x710 network interfaces  {not 82599  in article}
- Dual tagged traffic is being sent to the host VF {rather than the guest tagging the traffic in article}

So question is - can SRIOV VF port work with "QinQ / 802.1ad double tagged" to a compute node running RHEL 7 using an Intel x710 NIC


Our environment is a DPI application running in the Openstack instance VM. The DPI application needs to receive all traffic via the SRIOV port, and does not tag traffic inside the VM. Effectively a "port mirror" if you like.

The traffic is already QinQ when it arrives on the PF on the actual NIC. 
	We do not wish to add, nor remove any tags. 
	We simply wish to pass the input frame "raw" from the NIC PF to the VF and into the VM (as VM's "eth0")
	When the VM goes promisc on it's eth0 (which is the SRIOV VF thats exposed to the VM), It should see everything that came in the physical NIC port.
