12 description:
13 Modern networking hardware implementing the Open Compute Project ONIE
14 infrastructure shall provide a non-volatile memory with a table whose the
15 content is well specified and gives many information about the manufacturer
16 (name, country of manufacture, etc) as well as device caracteristics (serial
17 number, hardware version, mac addresses, etc). The underlying device type
18 (flash, EEPROM,...) is not specified. The exact location of each value is also
19 dynamic and should be discovered at run time because it depends on the
20 parameters the manufacturer decided to embed.
