I think some update has caused this to happen, probably about 10 days ago (noticed
something was slow). These are KDE/Plasma GUI systems but I'm not sure if this is
due to a change in KDE/Plasma, NetworkManager or something else.
On these systems the KDE/Plasma NeworkManager settings GUI interface now has an
"Allow auto-negotiation" checkbox which I don't think was there before and
it looks
like this is set to non-auto, 100MBit/s, half duplex by default if there is no
ETHTOOL_OPTS="autoneg on" in the /etc/sysconfig/network-scripts/ifcfg-* file
and on
initial setting of a network interface.
Here is a screen shot of an F24 Live system showing "autonegotiate" has been
there
for quite some time.

I guess this is a change/bug in the KDE-Plasma network manager applet. Where should
I file this bug ?
I'm not seen any problems on any of my systems.
What is the output of "ethertool <devname>" ?
