Starting at Kernel version 4.15, the connection is constantly lost, followed by reconnects. Kernel version 4.14.11-041411-generic still worked perfectly fine. I also tried the newest release, 4.17-rc6, the issue has not been resolved. My Mainboard: MSI 970A-G43

The Windows default driver version 9.1.406.2015 did not suffer from that issue. In Windows, the issue is resolved by reverting back to the old driver or by using the new driver and disabling "Energy Efficient Ethernet" in device manager driver settings. Trying to disable "Energy Efficient Ethernet" in Linux using "ethtool --set-eee enp5s0 eee off" returns "Cannot get EEE settings: Operation not supported" Could the implementation of a malfunctioning new driver version into the Linux Kernel be the culprit?
