Oh!  I didn't even realize this.  I don't know much about RedBoot
honestly.

When I get a chance, I will submit a patch with CDL that when enabled
will automatically start a thread on startup to poll to ethernet.  As
far as I can tell, this should be entirely portable to any eithernet
driver shouldn't it?

I need to get to understand the ethernet driver API to the IP stack
anyhow, so I'm looking for a project to do.
