Ah, finally someone else sees what I ran into last year. Look for my posting to -current in May 2001, subject "dc0 ARP problem with CISCO". At that time, the only advice I got was to hardwire speed detection (which didn't help). My solution then was to switch hardware :-( So I'm afraid this is of no help to you, except for the "mee too" confirmation. -- Regards, Georg.
