Well, that is device/driver dependent and I don't know what's the case for this driver. It's encouraged to shutdown hardware completely (except the WOL parts) when the interface is down. Dunno if this driver does it. But _if_ it does it, it could cause problems to poke with the hardware while down. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
