Thanks Mikael.

Anonymity has some good attributes.
Blame avoidance is one of them.

I've broad shoulders. It's me, then Dwight Howard...

There might be another few of these where ->name or ->dev
was used before struct device or net_device was registered.
I'll go back and check.

tulip_core has:

if (tp->flags & HAS_MEDIA_TABLE) {
sprintf(dev->name, DRV_NAME "%d", board_idx); /* hack */
tulip_parse_eeprom(dev);
strcpy(dev->name, "eth%d"); /* un-hack */
}

So I don't feel _too_ bad.

tulip_parse_eeprom is done before register_netdev so the logging
there can not use netdev_<level> or dev_<level>(&dev->dev
