| 12 | * Multi-function PCI cards are supposed to present separate logical |
| 13 | * devices on the bus. A common thing to do seems to be to just use |
| 14 | * one logical device with lots of base address registers for both |
| 15 | * parallel ports and serial ports. This driver is for dealing with |
| 16 | * that. |
