I've been having the same problem after resume. However, although de-
modprobe-ing and re-modprobe-ing enables the 'eth0' to be renamed as
'enp2s0', finally it fizzles out with

Past similar reports related to r8169 over the years:
2017 - https://askubuntu.com/a/893823/723997
2011 - https://ubuntuforums.org/showthread.php?t=1661489
- This 2011 one is interesting because the author points out that ::
# lspci | grep Realtek
02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
RTL8111/8168/8411
PCI Express Gigabit Ethernet Controller (rev 0c)
so he replaced r8169 with r8168 and succeeded.
On the other hand, the following set of reports seems to indicate that
it is independent of the driver, because of multiple cases where
unloading and loading the driver solved the problem although the drivers
are different:

In conclusion, there might be a deeper bug which is appearing and
disappearing with different versions depending upon the random module
layout in the compile.

Title:
r8169 ethernet card don't work after returning from suspension
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Bionic:
Fix Released
Bug description:
===SRU Justification===
[Impact]
Ethernet r8169 stops working after system resumed from suspend.
[Test]
User confirmed these patches fix the issue. r8169 continues to work
after resume from suspend.
[Regression Potential]
Medium. The fix is limited to one device, all patches are in mainline.
The WOL default change might cause regression for users that depend on
BIOS settings. We can advice them to use userspace tool (systemd,
ethtool, etc.) instead.
===Original Bug Report===
I have noticed that the network stopped working on my desktop after I've
suspended the system and woke it up. On dmesg there are messages like:
[ 150.877998] IPv6: ADDRCONF(NETDEV_UP): enp1s0: link is not ready
[ 150.944101] do_IRQ: 3.37 No irq handler for vector
[ 150.944105] r8169 :01:00.0 enp1s0: link down
[ 150.944180] IPv6: ADDRCONF(NETDEV_UP): enp1s0: link is not ready
When using Xenial (from a different install), this problem is not
happening. This is happening on Bionic.
There are only two ways to restore connectivity:
1) Reboot the system;
2) Remove the r8169 module and reinsert it with modprobe.
The motherboard is a AsRock H55M-LE and the Ethernet controller is:
