I don't think the compiled-in MAC address should be used at all.
For most boards, the compiled-in option is just some random MAC address. When
the board is shipped, the manufacturer creates his own set of environment
variables and overrides what's stored on flash.
I actually think that storing a MAC address in a board configuration for or a
DTS is a bad idea, because MAC addresses are supposed to be unique for each
Ethernet device, and storing a fixed value in a source file breaks that.
However, that's a separate issue. I was just trying to stress that the
compiled-in MAC address is of no value.
