My system is basically a Lenovo minitower desktop with a SSD SATA disk.
Nothing peculiar. Please find attached lshw.txt and lspci -vv, if that could
help.

ASPM is reported as OK for all PCI devices (PCI-E root and RTL8198h). I guess
for a desktop ASPM is not all that critical.

All my RFC PATCH actually disabled CLKPM, however the lack of intel made me
recompile rather than do the runtime switching off. Kernel docs are unfortunately
around 2010 on PCI Express. :-(

I think that the problem might be in our Mikrotik RB2011 UiAS-RM which still
has Fast Ethernet ports and must be 15 years old and most likely doesn't support
CLKPM so odd things happen ...

But Windows 10 default is faster as I said, and I can't tell how many Linux
users will figure out to turn off CLKPM via sysfs ...

I saw that you had regressions with the fix I proposed (which is in fact
almost entirely based on your patch and applied to the different file as
the code was somewhat reorganised). I can simply run it at boot in a unit or
from cron, but sort of feel that the most sensible setting should be the default.

I wasn't lucky with finding RTL8168h specs, so I guess I can only keep my fingers
crossed for your zero copy and io_uring implementation of r8169.

We are really out of luck, but RTL is so ubiquitous and I think higher powers
would appreciate this driver debugged. ;-)
