I prefer 999999999 as it's something that looks slightly less "magic
number"-y (plus looks like the other devices in igb) and is still
technically something that can be passed down without error. Ultimately
not a big deal and I can understand your argument, so I'm okay putting my
personal preference aside on this one.
