Previously, it was assumed that only PCI NICs would be capable of having virtual functions - with my proposed enhancement of dummy NIC driver implementing (fake) ones for testing purposes, this is no longer true.
Discussion of said patch has led to the suggestion of implementing a bus-agnostic method for VF count retrieval so rtnetlink could work with both real VF-capable PCI NICs as well as my dummy modifications without introducing ugly hacks. The following series tries to achieve just that by introducing a bus type callback to retrieve a device's number of VFs, implementing this callback for PCI bus and finally adjusting rtnetlink to make use of the generalized infrastructure.
