--- Comment #3 from Mark Stutter ---
I did some more checks and have an important update on this issue:
If I switch the network setup to be managed by "wicked service" in yast2 the
card is recognized as 1000Mbit/s and all works fine!
Switching back to NetworkManager it is recognized as 100Mbit and it is slow
again.
This is consistently reported by ethtool and dmesg.
The relevant part of the output of dmesg when switching from wicked to
Networkmanager is:

I think it is in the line "[ 498.170363] e1000e: enp0s25 NIC Link is Down"
that the network interface is shut down when yast switches from wicked to
NetworkManager.
before (wicked):
e1000e: enp0s25 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: None
afterwards (NetworkManager):
e1000e: enp0s25 NIC Link is Up 100 Mbps Full Duplex, Flow Control: None
I have no idea why that happens ... is it ultimately just a NetworkManager
issue? But the speed of the card should be managed by the driver, right?
In opensuse Leap it seems to work fine.
