The underlying device type (flash, EEPROM,...) is not specified. The exact location of each value is also dynamic and should be discovered at run time because it depends on the parameters the manufacturer decided to embed. select: false properties: compatible: const: onie,tlv-layout product-name: type: object additionalProperties: false part-number: type: object additionalProperties: false serial-number: type: object additionalProperties: false mac-address: type: object description: Base MAC address for all on-module network interfaces.
