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. | |
