I have been busy and unable to look at this until today.

That's the right driver. One thing you could try is after removing the
module, try "modprobe r8169 debug=n" where n is a number up to 16. That
will give you more debugging info in the log. Careful, 16 might really
spam the log, so maybe start at 8 and work your way up.
Going to 16 didn't make any difference from 10.

The driver is saying that there is no link detected. Are the lights on?
What does "ethtool enp4s0" tell you?
Link lights on switch come up when lid closed and opened without
reloading the network driver.
ethtool shows Link detected: no which is interesting.
Looking further into the log files, I don't seen any mention of r1869
before March 17 when I tried to make a change to the boot parameters
from something I found on the net which was almost a month after the
problem started.
pci=nomsi,noaer
I would suggest removing this.
My guess, given that reloading the driver makes it work again, is that
after resume, the driver is not turning some part of the chipset back
on. Maybe the interrupts are getting turned back on.

What does "grep r8169 /proc/interrupts" give you when the interface is
working? Try it a couple of times and see how the numbers change. Then
when it's not working try it again a few times and see if the numbers
are still changing.
This is from /proc/interupts and doesn't change between suspends or
disappear. It is there from boot until I remove the module.

It used to work until February but I don't know what update affected it
as I wasn't told until a few kernel updates that there was an issue.
What I found that is when I load the module, lsmod give me this.
r8169 94208 0
mii 16384 1 r8169
I am going to look more at the mii-tool and see if that has anything to
do with it.
I did find another thread about kernel modules being broken in February
and specifically mentioning r8169 module not reloading on suspend.
