For a single function device, only INTA# may be used while the other three interrupt lines have no meaning. And: When several independent functions are integrated into a single device, it will be referred to as a multi- function device. Each function on a multi-function device has its own configuration space. So this is not easily virtualizeable. I think in practice it should be only legal to assign VFs or all functions of a physical device in one go. In last case, we can then make sure function numbers match.
