-proposed solves the problem. Please test the kernel and update this bug
with the results. If the problem is solved, change the tag
'verification-needed-lunar-linux' to 'verification-done-lunar-linux'. If
the problem still exists, change the tag 'verification-needed-lunar-
linux' to 'verification-failed-lunar-linux'.


If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

Bug description:
  [Impact]
  Intel I219 ethernet stops working after system sleep.

  [Fix]
  Force resume Intel ME to fix I219. It's not surprising because ME/AMT is
  controlled through Intel I219.

  [Test]
  Use `ping 1.1.1.1` to test if I219 is still alive. With the patch
  applied, the ethernet can survive several system sleeps.

  [Where problems could occur] 
  The commit essentially disables direct-complete optimization, so it
  will make system suspend/resume slightly slower.
