Thanks, this makes clearer what's going on.
This change to r8169
bde135a672bf ("r8169: only enable PCI wakeups when WOL is active")
removed marking the device as wakeup-enabled to work around an
issue on certain notebooks (see commit message for details).
ethtool doesn't care about the current settings and sets the new ones
(wakeup-enabling the device). systemd however checks the current settings
and writes new ones only if there's a change. Therefore in your case
systemd does nothing and device doesn't get wakeup-enabled.
Not totally clear to me is why it works under 4.18.
And I wonder why the following didn't work for you, you said it makes
no difference. Could you try again the following in addition to the
latest debug output statement?
