  [Fix]
  Intel provides a patch to fix this issue which is landed in v5.17-rc7
  1866aa0d0d64 e1000e: Fix possible HW unit hang after an s0ix exit

  [Test]
  Verified by ODM on Dell machines

  [Where problems could occur]
  The fix disable PHY reset when runtime suspended, the PHY will be reset after 
resumed. So, it should not introduce any regression.

  [Misc]
  Jammy(5.15) has this fix through stable update.
