Public bug reported:

[Summary]

During the SRU testing, I found a hp laptop always timeout after suspend
test, after checking I found that the NIC didn't link up.

Part of journal log as follows:
Sep 12 11:13:01 ubuntu kernel: PM: suspend entry (s2idle)
...
...
Sep 12 11:13:10 ubuntu kernel: PM: suspend exit
...
Sep 12 11:13:14 ubuntu kernel: r8169 0000:02:00.1 enp2s0f1: PCI error (cmd = 
0x0407, status_errs = 0x0000)

[Expected result]

SRU test can continue after suspend test.

[Actual result]

SRU test times out and NIC is down.
