I don't see how the improvement to the r8169 driver and the issues deep
in the network stack should be related. Was the referenced r8169 commit
result of a bisect?
The Debian kernel may include additional Distro-specific patches.
I'd recommend re-testing with mainline kernels.

Also 4.19 has been out for quite some time and boards with r8169-driven
chips are very common (basically every consumer mainboard). In case of a
general driver issue I'd expect to have received more such reports.
Do you use any special network features on your system?
