Can we not do this with a single i2c_read() call with length = 6 ?

Yes we can, but it is safer this way in the case when ethernet address spans across two chips. Rest of comments addressed in version 7 of the patch which will be sent soon.

Is such a scenario (MAC address split across 2 different EEPROM devices) possible (and supported) on these systems?

Best regards,
