This is interesting. Do you mean you can put a shaper on a specific VF
queue from hypervisor? I was thinking about it recently, I have some
concerns.

In general a nic user expects all queues to behave in the same way,
unless he does some sort of configuration (dcb for example).
VF (the VM side) is not different, it's also a nic.

If you allow the hypervisor to configure shapers on specifig VF queues,
you are breaking VM's user expectation. He did not configure any
different queue treating, yet they are treated differently.

Is that okay? What do you think?
