No it's not.  That info is in the "local-mac-address"
property, instead.

"mac-address" contains the address OF used for the device;
it should only be there _if_ the firmware used the device,
and it can only be different (if it is present at all) from
the "local-mac-address" if you are on ancient hardware.

Don't use "mac-address" in flat device trees.  Use
"local-mac-address" instead.
