Public bug reported:
Steps to reproduce:
1.) Start Ubuntu, with LAN plugged in, login
2.) Verify Network Manager detects the Wired Connection
3.) stop Network manager
4.) unplug LAN cable
5.) start Network manager
Result: Network manager doesn't detect that eth0 is not in RUNNING state
Plugging in LAN cable doesn't change state either, i.e. eth0 remains
unconfigured.
