Comment(by lindi):
I finally managed to build a cable to measure the consumption. I connected
{{{
Bus 002 Device 094: ID 0fe6:8101 Kontron (Industrial Computer Source / ICS
Advent) DM9601 Fast Ethernet Adapter
}}}
to my PC and put a 0.1 ohm resistor in series. I then measured the voltage
over the resistor:
{{{
after plugging in: 19.0 mV
after ip link set eth3 up: 19.2 mV
after connecting to a switch: 21.8 mV
}}}
