T= he issue is not a big deal but one we would like to solve. we have no way = of signaling an upstream router that a path is down but via turning off the= link of the ethernet port.

We can modify the system so if it means modifying the driv= er or some other code, I am willing to try. Just need a little direction. Marius talked about doing this. Maybe it's time we added it as a device option, so people can have the PHY disabled when the NIC is brought down? Adrian
