Want support for I350 temperature sensor
The Intel I350 which is supported by the
igb driver has a built-in thermal diode and optional support for an external temperature sensor indicated in its eeprom. This change adds support for the built-in thermal diode as I have not been able to find a discrete I350 with these features enabled in its EEPROM yet. Though extending it in such a case would be useful. This leverages the framework introduced in 12830.
