Description of problem:
Laptop with Fedora 27 cannot connect via Ethernet to a network after sleep (not hibernation).

Version-Release number of selected component (if applicable):
Fedora 27


How reproducible:
Always

Steps to Reproduce:
1. With connected or disconnected Ethernet cable (in my case doesn't matter) turn on sleep mode on a laptop.
2. Turn off sleep mode.
3. Ooops: Ethernet doesn't work (and even isn't detected). 

Actual results:
There is chance to get workable Ethernet connection after sleep.

Expected results:
Fedora should be able to establish Ethernet connection after sleep.

On Windows 10 all works fine. Ethernet cable is fine (tested on Windows and on another machine).
