Darrell,
Thank you for the resources and the response.
I am not using a Linux bridge at host. Just SR-IOV to pass through the

The topology diagram provided makes it clear that all the packet flow is
internal to a single PF.
Maybe check that the nic bridge is working as expected; you don’t need OVS
