this would be used as a name when exporting the data, however you are
right and the property name lanmac could be used here

in my usecase there will be only 1 ethernet device. the mac is stored
inside the devices flash and will not be passed as a parameter by the
bootloader. We need to have some means to load things like mac addresses
from memory mapped flash devices. This is the reasoning behind this wrapper
