I'm not familiar with the Pandaboard but most of the devices I've worked
with that do this have unique MAC addresses but they store in other
locations on the device (typically in flash).
Like I say, it's not just MAC addresses that can need configuring this
way - it can be other random "you're wired up this way" type
information that would normally be figured out from the USB IDs.
