It is not necessarily superior, but works.
One situation it is better (not that I have seen this used) is if the
ethernet driver needs to reset the hardware ethernet. If it doesn't know
the MAC, you are now without a MAC address.

It also means you depend on the state of the hardware. You cannot jut
issue a full reset to the etherner chip, and set it up fully from there.
