Board revision depends from the address of the eeprom wich can be 0x50, 0x51, 0x52, 0x53. there are configurations where 0x51 is used as address for RTC. 0x51 can be the address of the eeprom only if the probe of the others addresses don't work
Update get_macaddress_from_eeprom for use the correct eeprom address depending on the board revision
