Ethernet network drops often, which is detected as a disconect by a
station on port 4. Also visible in dmesg:

This has been tested with two different Archer C7 v2.0 boxes. It is not
associated with cabling or the connected station on port 4, because the
setup works if I replace the Archer C7 with a D-Link DIR 825 with the same
trunk version and configuration.
This also happens if I connect the station on any other LAN port.
