The VPD is not really the firmware EEPROM. The real EEPROM is behind
an SPI interface, that maybe supported in later version.
Programming the VPD through the ethtool interface doesn't work
(doesn't really change firmware). Now that the interesting bits are
available through the debug interface and raw data is available through sysfs,
the old ethtool eeprom interface can go.
