I checked the 8169 doc. In the EEPROM section there is the following
description for EEPROM address 0xe - 0x13:
"Ethernet ID: After auto-load command or hardware reset, the RTL8169
loads Ethernet ID to IDR0-IDR5 of the RTL8169's I/O registers."
As that happens automatically after reset, I would suggest that re(4)
should trust IDR0-IDR5 for the correct address, and not try to access
the EEPROM itself - which might be missing.

Your are right. The address read from EEPROM is the same on two different
machines. Probably because it uses default values when the EEPROM is
