Tying down network interfaces

[Martin Birgmeier]

Hi,

I have two network interfaces as follows:

sis0: <NatSemi DP8381[56] 10/100BaseTX> port 0xa400-0xa4ff mem
0xd5800000-0xd5800fff irq 9 at device 9.0 on pci0
sis1: <NatSemi DP8381[56] 10/100BaseTX> port 0x9400-0x94ff mem
0xd4800000-0xd4800fff irq 11 at device 12.0 on pci0

When sis0 breaks down, sis1 gets renumbered as sis0, wreaking havoc
(mostly on my brains until I figure out which card is actually affected).

How do I tie down these two interfaces so that they always stay as sis0
and sis1, respectively, regardless of which ones are present in the
system? - I expect to insert something into /boot/device.hints.
