NetBSD/sys/dev/pci/pci_quirks.c
cgd 3e3f8b7bac dd a PCI 'quirks' mechanism, meant to be used as the mechanism
of last resort when trying to communicate information about
bogus behaviour of PCI devices to the MI autoconfiguration code.
In general, bogus behaviour should be handled by drivers, but there
are some types of bogons which can't be addressed that way.  The
only quirk currently defined is one which indicates that the device
is multi-function even though the device's header says otherwise.
(Mmm, Intel 82371FB PCI-to-ISA Bridge (PIIX); you'd think that at least
Intel would have gotten it right...)
