Unfortunately, it's not quite that simple, since Network Manager is
configured by default to ignore Ethernet connections.  I think this is
something inherited by Debian.

There is a proper way to correct this by adding a higher priority
configuration file in /etc

Personally, I've just been deleting
/usr/lib/NetworkManager/conf.d/10-globally-managed-devices.conf
