Way too late, I think, since the driver would have to attach before it could even query the card for its MAC address. If it were able to get the MAC, detach, re-attach, etc. until the right order was reached, that might work. > Hmm.. maybe some sort of aliasing?

I like that. I'll bet someone will come along and tell us why it isn't feasable, though. The biggest problem I can see is that network devices have never had device nodes, so they would truly have to be "symbolic" in more than one sense. :-) -- Chris Dillon - cdillon@wolves.k12.mo.us - cdillon@inter-linc.net FreeBSD: The fastest and most stable server OS on the planet.
