Description of problem:
Network link is not detected in kernel release 4.16. The on board link LED indicates a link but ip l / ethtool reports no link detected.
Booting with 4.15 results in an working link.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Using a Asus XG-C100C 10G Network Adapter
2. Boot with kernel-4.16.4-200.fc27.x86_64
No link is reported by OS however card is indicating a working link via the onboard LED (also on the switch).
The link should be reported as up the same way it is in 4.15
This has been fixed upstream, kernel bug 199177
This is now fixed in kernel-4.16.6-202.fc27.x86_64
