Hi Alex
Going through the PCIe Spec, there seems a lot of such capabilities that are different between PF and VF. Some that make sense and some don't.

For e.g.
VF doesn't have I/O and Mem space enables, but has BME Interrupt Status Correctable Error Reporting Almost all of Device Control Register.
So it seems like there is a ton of them we have to deal with today for VF's. How do we manage to emulate them without any support for them in VF's?
