The devices all come up with wiith unitid of 0 and are scanned depth
first just as pci bridges are. The unitids can be set automatically
but usually some devices are set specifically. The subtractive device
is normally left as device 0. In the case or Serengeti it is 6 for
historical reasons (  think there was a early 8111 bug that required
the setting).
