PCIBUS_MAX_DEVICES is the size of PCIBus.devices[], I have added it in
the first patch at the defination of struct PCIBus, line 50 hw/pci.c.
so i think the better name of the macro should be PCIBUS_MAX_FN,
right?

PCIBUS_MAX_DEVICES is the size of PCIBus.devices[], I have added it in
the first patch at the defination of struct PCIBus, line 50 hw/pci.c.
so i think the better name of the macro should be PCIBUS_MAX_FN,
right?
