Describe the bug
connection.port_link reporting error as below.

Environment (please provide the following information about your setup):

• Hypervisor: Proxmox VE 8.2.2
• Host Operating System: Ubuntu 24.4.01
• Testrun 2.0.1
• Additional hardware (network adapters): USB Ethernet adapter (passed through)

Additional context
All other tests working as expected, just connection.port_link.

It appears that more than just the port_link test has issues with your setup.

port_speed and port_duplex are both failing because the device is reporting configuration of half duplex. You may need to change your VM to bridged adapter instead of pass through. This has been a reported solution to this issue.

Concerning the port_link, can you test the command ethtool -S on the adapter in question outside of the VM? The stats that are missing in the current test are tx_errors and rx_errors. If the device can't report these values then you will need to use a different adapter that does. Unfortunately, there is not an official list of supported devices at this time.

I believe this has already been fixed in dev (at least better handling of the error).

After checking the dev branch, I can see that we fixed this. The test will give the result of Error and will give the description: Port stats not available

Just confirming for info below.

• enxc8a3623d11e5 is the adapter I was using during the test in the OP.
• enx3c18aOd5708f is another adapter that I've used successfully on other machines.

Above output printed from inside the VM.

Just for additional info, ifconfig does provide tx and rx error information for the two Ethernet adapters in question.
