I need to correct myself: the card stopped working out of the blue and
started to print Tx status -71 to dmesg. So the statement "network works
perfectly while the computer is turned on" is not true.
Excerpt from the dmesg:

Interestingly, the card does not seem to act as an USB device, but
rather as a PCI device. That's weird, since the card is located on a
docking station which is connected to the computer via USB. I guess this
is because Thunderbolt-over-USB or similar?
~> lspci|grep -i eth

BUT the Network Manager says "USB Ethernet" for the docking station
ethernet port, so perhaps the PCI device refers to the ethernet "dongle"
which can be attached to the computer? Yes: Network Manager says "PCI
Ethernet Connected" when I plug the cable into the dongle.
Found it:
