Investigate dropping etherlike interfaces since setting speed/duplex works on virtio interfaces

          Very interesting! :eyes: 

Wasn't this the whole raison d'être for the ethernet/etherlike split?

Autoneg-support can be detected using ethtool, so that should not be a problem to avoid on these interfaces. Since we can set the speed, shouldn't we get rid of etherlike all together?

Then you could set the speed to whatever you want in the config instead.
