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.

Everything is working marvelously, but from time to time the ethernet port on the docking station won't connect. I've discovered the following messages in my dmesg: [ 400.597506] r8152 5-1.1:1.0 enx482ae3a2a6f0: Tx status -71 [ 401.164370] r8152 5-1.1:1.0 enx482ae3a2a6f0: Tx status -71 [ 463.168412] r8152 5-1.1:1.0 enx482ae3a2a6f0: Tx status -71 [ 465.314415] r8152 5-1.1:1.0 enx482ae3a2a6f0: Tx status -71 [ 529.409871] r8152 5-1.1:1.0 enx482ae3a2a6f0: Tx status -71 [ 533.718163] r8152 5-1.1:1.0 enx482ae3a2a6f0: Tx status -71 [ 591.168537] r8152 5-1.1:1.0 enx482ae3a2a6f0: Tx status -71 [ 594.335383] r8152 5-1.1:1.0 enx482ae3a2a6f0: Tx status -71 Rebooting the machine doesn't seem to work, turning the ethernet connection off and on doesn't seem to work. I have a dualboot Linux+Windows (one wants to play games from time to time :-p ) and it could be that rebooting from Win to Lin causes this issue, but this needs to be confirmed yet. I will try to power off the computer and/or the docking station, to see whether that would help. I've found numerous bug reports, but they are rather old or may not apply to this situation, therefore I figured it's best to open a new bug report. Thank you so much for your hard work!
