Hi Andrea,

first things first. What kernel version are you using?

I looked at the latest version (2.6.38), and I saw that in include/linux/i2c/at24.h there is a structure to access the eeprom data. You should initialize that structure in your driver, or at boot, making it point to the eeprom address where the mac address is located.

The standard way is always through the api's given in header files under the "include" directory.

Hope this is helping,
