Re: query on multiple pci adapter suppport

Yep. I/OKit will instantiate one driver for each port on the adapter (like in the case of a 4-port ethernet card).

See IOPCIBridge and IOPCIDevice, both in IOKit, for the conceptual underpinning behind this. A multi-port card will usually have a PCI bridge on it, so IOKit will detect this and assign an IOPCIBridge as the abstraction to represent it. Then each port on that bridge will be assigned an IOPCIDevice to represent it.

Quite cool...

Does MAC OS X IOKit support driving multiple PCI adapters of same kind with
