As a workaround we can use powertop. Using this tool as root (sudo
powertop), go the "Tunables" tab using left/right keys and toggle the
correct entry, in my case it was "Runtime PM for PCI Device Intel
Corporation 82577LM Gigabit Network Connection".
Once this entry as been switched to "Bad", I can plug the cable and the
interface status is set to up.
This workaround has to be set each time the power cable is unplugged.
