Hrm. If it's intended to be optional, that implies that BDS not having
a special case for when they don't match is a bug, doesn't it? There's
no way when you're generating a device path to put in the Boot####
variable whether a device's driver is going to use 0 or (in the ethernet
case) 1.
So if it's truly optional, Doesn't BSD need code to treat it optionally?
