Re: [Etherboot-developers] why does scan_bus() in pci.c ....?

[Ken Y. <ke...@nl...>]

|I am corrected. The fault is mine. It derives from my project requirement to
|identify, not just the first, rather all the ethernet adapters on the bus.

What you probably want to do is pass an array of addresses and an array
PCI structures instead of just one, say limited to 2 or some compile
time constant. Then you can pass these arrays from the caller in
config.c.  (Etherboot has no support for heap allocation, keeps things
simple and avoids problems with memory allocation.) The number of
candidate NICs found can be indicated by terminating the pci_addr array
with a 0.
