[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.
