===SRU Justification===
[Impact]
e1000e stops working since 4.13.0-38-generic/4.13.0-1022-oem.
The regression was introduced by patches in LP: #1730550.
[Fix]
Commit 4110e02eb45ea447ec6f5459c9934de0a273fb91 fixes the issue.
e1000e now reports correct link status.
[Test]
With the extra commit, the e1000e starts to working again.
[Regression Potential]
Low.
It says:
Fixes: 19110cfbb34d ("e1000e: Separate signaling for link check/link up")
So it's pretty clear this patch is to fix the regression.
It's in upstream linux-stable, so only Arftul needs this patch.
