And since it's your ethernet device that's reporting the messages (not very
well - if it did it on a single line, the log daemon would simply
report "previous message repeated xxxxxxx times" and not fill your disk!),
what driver does it use?

Is the network interface working?  You could experiment with the log
settings to try to suppress those specific messages.  Certainly they don't
need to go to all three files, though if either one could be suppressed you
wouldn't have a problem (assuming that the ethernet device actually works).
