Yeah, I've only seen domains used on huge SGI machines. 256 PCI buses
are quite a lot for a normal machine. :)

They don't share the numbers, yeah.

We could add a P<domain> or m<domain> in front:
  enP2p32s15
  enm2p32s15

Or something else, we just have to pick one. :)

And we would suppress that for all the common domain == 0x0000 cases.
