When using the Fedora29 KDE spin iso Fedora-KDE-Live-x86_64-29-1.2.iso,
the system configures the Ethernet interface to 100 Mbits/s by default
on my systems. Has anyone else noticed this ?
The "Auto negotiation" setting is not enabled by default. Once "Auto
negotiation" is set, using the NetworkManager, all is then fine. This is
on 3 different systems now.
I'm not sure if this is a general Fedora29 bug, or a KDE/Plasma issue. I
know there was a bug related to this in Fedora27 which I reported many
moons ago ...
