Currently the zPCI code blocks PCI bus creation and probing of a zPCI zbus unless there is a PCI function with devfn 0. This is always the case for the PCI functions with hidden RID, but may keep PCI functions from a multi-function PCI device with RID information invisible until the function 0 becomes visible. Worse, as a PCI bus is necessary to even present a PCI hotplug slot, even that remains invisible. With the probing of these so-called isolated PCI functions enabled for s390 in common code, this restriction is no longer necessary. On network cards with multiple ports and a PF per port this also allows using each port on its own while still providing the physical PCI topology information in the devfn needed to associate VFs with their parent PF.
