after you yank the cable, what happens if you run mii-tool ethX . Does it
say that the link is dead? If so, what I do is run mii-tool in monitor
mode and just look for a "link down" statement in syslog. When it arrives,
I down the interface with no cable. Not the most elegant, but it has
worked for me for some time now.
