            Bug ID: 203769
           Summary: Regression: Valid network link no longer detected
           Product: Networking
           Version: 2.5
    Kernel Version: 5.2.0-rc2
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Other
          Assignee: stephen@...workplumber.org
          Reporter: gwhite@...ulau.com
        Regression: No

Commit 7dc2bccab0ee37ac28096b8fcdc390a679a15841 has broken wired networking on
two of my machines.  Drivers e1000e, igb and r8169 all fail to detect link with
this commit applied.  The drivers load and appear to initialize correctly, but
no link is ever detected.

With this commit reverted, they work perfectly.

This is on a fully updated Arch.  Happy to provide any other information that
is of use.
