Thanks a lot Garrett!! Your response is very helpful. I have some follow-up questions that hopefully you and others may be able to help me with.
I was hoping for something that would work in general including on Solaris 10 / bge (not sure if the any of the drivers with PHY disabling capabilities is part of Solaris 10). It's possible that something less severe than completely turning off the PHY will still do the job (I doubt turning just the MAC off will). I just want to be able to make one side detect that a link is down based on a software action on the other side of the link. For example if I just connect 2 Solaris machines with a crossover cable (no switches or anything in between), will it be possible for one machine to manipulate the link state in a way that the other machine will report (with ifconfig or kstat) that the link is down? Is it possible to use ndd to advertise a faulty or offline link state using the adv_rem_fault parameter? (Fault value reported by the local system to the peer) or perhaps try to force a speed mismatch on the link (also using ndd) hoping this will lead the peer to detect the link is not usable. Taking bge driver as an example, I was not able to confirm whether it supports adv_rem_fault.
