Ah, I see. So, today, of all the devices labelled as "pci" which
QEMU has, how many of them are in which of those categories?
(I guess I'm mostly interested in whether what we have is
mostly really-PCI devices with one or two PCIe devices, or
if we're currently (mis-)modelling some PCIe devices as hybrid.)
