I have bounced the original message there. Sorry for missing that, I was
not aware that the MAINTAINERS file goes down on a single driver level.

I do enable WOL via systemd-networkd:
[7/5009]mh@fan:~ $ cat /etc/systemd/network/10-lanc0.link
[Match]
MACAddress=54:04:a6:82:21:00
[Link]
Name=lanc0
WakeOnLan=magic
and I wake up the box by calling
sudo etherwake -i int182 54:04:a6:82:21:00
on the router. int182 is the interface name of the correct interface,
this is proven correct by the fact that the box wakes up just fine with
older version of the driver.

The register dump is here (obtained with 4.20.1 with the r8169.c from
4.18):
