That's a known issue. For unmanaged devices, NM assumes the state to be offline.
I'm merging this with the existing bug reports.

See e.g. #491826 for more info.

There are some unofficial Ubuntu patches, which make NM always consider the
state to be online, for unmanaged devices. This also has some downsides, but is
probably more sane than to assume a offline state.
(at worst, apps will try to establish a internet connection and fail)

You need to restart the system settings service (see the README.Debian file I
referring to in my previous email [1])
sudo killall nm-system-settings


After that, NM should pick up you eth0 interface. An alternative is to configure
 eth0 via /e/n/i and set

[ifupdown]
managed=true

Cheers,
Michael
