The actual limitation is that we have only a single PCI bus.  The
network devices are single function devices.  While there are 32 slots
on the PCI bus, a few are already taken (typically the first 3, leaving
29 free slots).

But, as Markus mentioned, this limitation is only for legacy command
line option.  The modern qdev way[1] should not hit this same limitation.
