Thanks for the explanation.
So there's no way to determine this in advance.. I must build a script that contains my own mapping between MAC addresses and
the wanted interface names and run it after each driver load, rename the
interfaces if necessary.
It seems quite wrong, don't you agree?
And how come the unit number is given an arbitrary value? Is there a good
reason for that?

Normally the PCI probe runs in the opposite direction from that of Linux. It's largely to do with how the NEWBUS code walks the PCI bus. From a systems management point of view, yeah, it's irritating, however it would probably take more effort (i.e. kernel code) to try to patch it to work differently, and not everyone has free time to sit down and patch the kernel.

That and (unlike Solaris) there is no *direct* mapping between the card's driver number on the bus and its network driver number.

In your case I'm not sure why your two cards would flip order. Could it be how your BIOS and hardware set up the PCI IDSEL lines at boot?
