@Joseph: no point, as indicated multiple times, network card works with current kernel 4.12.0-13, when configured in /etc/network/interfaces
When similar was observed after upgrading of another system with completely different hardware: *-network DISABLED description: Ethernet interface product: 82566DC Gigabit Network Connection vendor: Intel Corporation I've noted that it was also *-network DISABLED This time search of the web led me to AskUbuntu entry [1] and the answer [2] advising to change NetworkManager configuration in /usr/lib/NetworkManager/conf.d/10-globally-managed-devices.conf this. Although I do not understand if there are other implications, this answer helped me to resolve issue at hand. Looks like this bug should belong to network-manager or other project dealing with configuration changes upon upgrades.
