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?
