The path in the HAL device tree is nothing more than a temporary place
holder. The consumer of this data uses the device supplied serial
number to uniquely identify it. After some of the email exchange
yesterday, I will augment that to use a MAC address based unique id if
the device doesn't supply a serial number of it's own..
