regression - r8169 network driver doesn't work after suspend

The dmesg log
Description of problem:
Kernel has a regression that prevents r8169 driver from working after a suspend-to-ram.
Version-Release number of selected component (if applicable):
4.2.6-301.fc23.x86_64 #1 SMP
Steps to Reproduce:
1. Boot the kernel
2. Notice that the network works
3. Suspend to ram
4. Notice that network doesn't work
I attach the dmesg log.
Network works as before.
This used to work in previous kernels - a regression appeared quite recently.
The 4.2.y kernel is rather old on F23 at this point. It has already been rebased to 4.4.2. Does this problem happen on the latest 4.4.2 kernel available?
It still fails on "Linux d33tah-pc 4.3.5-300.fc23.x86_64 #1 SMP Mon Feb 1 03:18:41 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux". This is the latest available in my F23 repo.
Still happens on 4.4.x kernels.
Possible duplicates: bug #1282254 and bug #1289499
There was no change in the r8169.c on kernel upstream, if you diff the git logs:
No directly related changes in fedora kernel git either. Seems like something outside r8169.c broke it.
It still happens in Fedora 24 with kernel 4.6.4-301.fc24.x86_64.
After resuming the driver reports link down, even ethtool reports link down.
Unloading and reloading r8168 module makes link up again.
*********** MASS BUG UPDATE **************
We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 23 kernel bugs.
Fedora 23 has now been rebased to 4.7.4-100.fc23. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel.
If you have moved on to Fedora 24 or 25, and are still experiencing this issue, please change the version to Fedora 24 or 25.
If you experience different issues, please open a new bug report for those.
NetworkManager still shows connection problems after suspend, but I haven't managed to reproduce a connection loss on suspend by trying 4 times. I disabled my workaround and will report back in case the issue is happening again.

After a week of running without my previous workaround the issue stays the same: Network connection doesn't drop any more, but NetworkManager still shows a question mark on its gnome-shell icon.
With kernel 4.7.4-200.fc24.x86_64 this problem seems solved to me.
Today I had this problem once again with kernel 4.8.4-200.fc24.x86_64.

I don't remember this from February, but this has happened to me three times in the last two days after upgrading to 4.8, too. My log looks pretty similar.
This message is a reminder that Fedora 23 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 23. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora 'version'
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 23 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
Thank you for reporting this bug and we are sorry it could not be fixed.
