Hi!
Yeah, exactly, that's it. And because igbe used the default case here (btw. we
had a discussion in irc about default cases at the beginning of the switch statement)
the some EEPROM stuff failed (there's also no bad EEPROM checksum message anymore),
resulting in a invalid mac address.
Thanks for this great remote diagnostics and keeping patient with me.
