Just curious, how do Panda boards manage to get the MAC address? Is it
programmed in some other flash memory?
The LAN9514 datasheet says
"If a properly configured EEPROM is not detected, it is the
responsibility of the Host LAN Driver to set the IEEE addresses."
So how does the Host LAN driver know what MAC address it should use?
