4.18.15 + PDS (custom CPU scheduler) + cherry pickings from mainline.
Applied both the original patch in this thread & bql, built fine.

Server:
r8169 0000:04:00.0 eth0: RTL8168evl/8111evl, c8:60:00:68:33:cc, XID 2c900800, IRQ 30

Workstation:
r8169 0000:04:00.0 eth0: RTL8168evl/8111evl, 50:e5:49:41:7d:ad, XID 2c900800, IRQ 33

So same chipsets.

On both:
ethtool --coalesce eth0 rx-frames 0 rx-usecs 50 tx-frames 0 tx-usecs 50
ethtool --offload eth0 rx on tx on gro on gso on sg on tso on

Let's see how it goes. :)

cheers
Holger
