Title:
After pm-suspend and resume, can't use rtl8169 NIC for networking
Status in linux package in Ubuntu:
Invalid
Bug description:
[Impact]
After pm-suspend and resume, can't use rtl8169 NIC for networking
[TestCase]
you need rtl8192 NIC on your machine
reproducer
1. pm-suspend
2. resume it
3. you can see a lot of err msgs in kern.log
and network connection keep changing in and out
There are around 4~5 commits from Chun-Hao Lin <[email protected]>
but it doesn't seem to fix this issue ( 100% sure, just cherrypicked
them but failed )
hwe kernel ( -edge as well ) didn't help
[Other info]
I can't test the other releases for this issue

below commit seems to patch this issue but not 100% sure (testing)
commit f09cf4b7832d029fb22d8f476eac12fc27dde61f
Author: Chun-Hao Lin <[email protected]>
Date: Wed Feb 24 14:18:42 2016 +0800
r8169:fix "rtl_counters_cond == 1 (loop: 1000, delay: 10)" log
spam.
There will be a log spam when there is no cable plugged. Please refer to
following links. https://bugzilla.kernel.org/show_bug.cgi?id=104351
https://bugzilla.kernel.org/show_bug.cgi?id=107421
This issue is caused by runtime power management. When there is no cable
plugged, the driver will be suspend (runtime suspend) by OS and NIC will
be
put into the D3 state. During this time, if OS call rtl8169_get_stats64()
to dump tally counter, because NIC is in D3 state, the register value read
by driver will return all 0xff. This will let driver think tally counter
flag is not toggled and then sends the warning message "rtl_counters_cond
== 1 (loop: 1000, delay: 10)" to kernel log.
For fixing this issue, 1.add checking driver's pm runtime status in
rtl8169_get_stats64(). 2.dump tally counter before going runtime suspend
for counter accuracy in runtime suspend.
