+title: NVMEM layout of the ONIE tlv table

+
+description:
+ Modern networking hardware implementing the Open Compute Project ONIE
+ infrastructure shall provide a non-volatile memory with a table whose the
+ content is well specified and gives many information about the manufacturer
+ (name, country of manufacture, etc) as well as device caracteristics (serial
+ number, hardware version, mac addresses, etc). The underlaying 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.
