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.
