- * MAC address.
- *
- * All-zero MAC addresses are rejected, because those could be properties that
- * exist in the firmware tables, but were not updated by the firmware. For
- * example, the DTS could define 'mac-address' and 'local-mac-address', with
- * zero MAC addresses. Some older U-Boots only initialized 'local-mac-address'.
- * In this case, the real MAC is in 'local-mac-address', and 'mac-address'
- * exists but is all zeros.
