Can you please elaborate what you mean by "create separate bus devices"

Just to clarify we are not creating separate bus devices for representors perse.
On our HW, there are multiple SRIOV PCI devices.
We are using one of those PCI devices (pci/0002:1c:00.0), to attach required hardware resources to it, for doing packet IO
Between representors and the representees. Once the HW resources (Rx, Tx queues) are attached to it 
we are registering multiple netdevs from this ie one rx/tx queue for one representor.
Beyond that there are no other bus devices being created/used.
