+
+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.
