Hi all.

There is no ex0 in my dmesg output.  With no network interface my only option is to transcribe by hand....

At any rate, the more general question is how to identify the device.  If it always displays the line with "MAC" and the MAC address, then that would be the answer I was looking for.

Based on the info you provided, it looks like the eon0 device is for OSI over IP.

Thanks!!
