Should we search for PCI devices by all classes to account for future support of drivers that are not part 
of the the Net class (e.g. netuio driver)? E.g.:
SetupDiGetClassDevs(NULL, TEXT("PCI"), NULL, DIGCF_PRESENT | DIGCF_ALLCLASSES);

Alternatively, since this patchset supports only RTE_KDRV_NONE, we can change it when introducing support for other types.
