I am currently running Vyos on a box that is utilizing intel i-223-v interfaces. I have put out of tree drivers into it to support 100/Full. When changing configuration in vyos to 100/full, it works without an issue, but when trying to change it back to auto, I get this warning:
WARNING: changing auto-negotiation setting on “eth3” is unsupported!
Looking at the interface, even though duplex is set to auto, and speed is set to auto, the interface still shows that Auto-negotiation is not on. I can change it to auto when utilizing ethtools, but not with Vyos configuration.
It appears that changing the speed to 100 and duplex to full, it changes the “supports auto-negotiation” to False, and changing the vyos configuration to auto for speed/duplex doesn’t reset it.
