ixgbe ufm support
To make it easier to read ixgbe's eeprom, we should add ufm support to ixgbe. Unfortunately the 82599 EEPROM map and most of the others don't have a notion of a concrete version of their own image, only of that of passed through firmware. For the time being we leave the image version as unknown as it is a bit OEM specific, we instead leave that for the moment as 'unknown', though we can revisit this after we dump a lot more eeproms and get more insight into what would be useful. e.g. if a Dell image version was there that might be useful.
