Public bug reported: [Summary]
During the SRU testing, I found at least 2 DUTs always timeout after suspend test, after checking I found that both of them only detect 10 Mbps speed on their NIC and can't get IP from DHCP. Part of journal log as follows: Sep 02 10:55:00 ubuntu kernel: PM: suspend entry (s2idle) ... ... Sep 02 10:55:11 ubuntu kernel: PM: suspend exit .... Sep 02 10:55:15 ubuntu kernel: e1000e 0000:00:1f.6 enp0s31f6: NIC Link is Up 10 Mbps Full Duplex, Flow Control: None [Expected result] SRU test can continue after suspend test and network speed should be 1000 Mbps. [Actual result] SRU test times out and network speed down to 10 Mbps.
