I have checked your problem on one of my systems and I also had it set

So, the question would be did your system once have "Allow
auto-negotiation" checked
but it became unchecked without action on your part? And what does
ethertool show to
be the current speed? Are you unable to set it to the desired speed?
I can select the desired settings and also enabling auto-negotiation
works, but for some reason it was set to 100/half without me doing
anything.
I'm not sure I ever touched those settings on that system before (and I
definitely did not set it to something this slow on purpose). I think it
was a new install of F26 with home directory carried over from earlier
Fedora releases and then updated to F27.
My understanding is that if one end (your PC) has auto negotiation
disabled while the other end (switch or router) has it enabled, the
link speed is set correctly, but the duplex setting falls back to
half-duplex. So that half-duplex setting is due to autoneg being off
for whatever reason.

The problem I had here was that the ifcfg-* file came from an existing
configuration (F25) and did not have the ETHTOOL_OPTS="autoneg on".
Normally I don't touch the Ethernet configuration, but if you do then
when you open the KDE-Plasma NM settings it will show this as auto neg
off, 100 MBits/ half duplex. If you don't notice this (maybe you are
just setting a static IP address), it will store the settings like this
and you get a forced 100Mbits/s mode. I think it should default to auto
neg if the settings are not given in the original file or if there are
no previous settings.
If think if you remove the default ifcfg-Wired_connection_1 file, reboot
and edit your network settings you will see this behaviour.
On top of this I "believe" 3 of my systems changed to 100 MBits/s within
the last few weeks without me setting any network settings, probably on
an RPM update of something.
