So long as the VF is exposed as a standalone PCI device, it's the same
interface. In fact you can take a random PCI card and expose it to a
guest this way; it doesn't have to be SR-IOV. Of course, with a
standard PCI card you won't get much sharing (a quad port NIC will be
good for four guests).

We'll need other changes in the network stack, but these are orthogonal
to SR-IOV.
