I have the same bug with 6.8.0-40 with another e1000e model (I217-LM, 8086:153a)
For me the 6.8.0-44.44~22.04.1 version from the kernel-team ppa fixes the
problem.

Title:
NIC speed down to 10 Mbps after resuming from suspend
Status in linux-signed-hwe-6.8 package in Ubuntu:
Confirmed
Status in linux-signed-hwe-6.8 source package in Jammy:
Triaged
Bug description:
[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.
[Additional information]
Following are the DUTs that are impacted.
