[-- Attachment #1.1: Type: text/plain, Size: 13140 bytes --]
[1.] One line summary of the problem: igc driver - Ethernet NIC speed not changing
[2.] Full description of the problem/report:
Trying to change my I225-V's connection speed to 1000 Mbps down from 2500 Mbps as a workaround to disconnection issues, but changes won't apply, regardless of using NetworkManager or ethtool.
NetworkManager displays the changed values, but they don't seem to actually apply.
Using ethtool to change the speed to 1000 Mbps (`ethtool -s enp6s0 speed 1000`) also fails.
The interface gets brought down then up with the same 2500 Mbps speed.
[3.] Keywords (i.e., modules, networking, kernel): driver, networking, igc, intel[4.] Kernel information
[4.1.] Kernel version (from /proc/version): Linux version 6.4.6-arch1-1 (linux@archlinux) (gcc (GCC) 13.1.1 20230714, GNU ld (GNU Binutils) 2.40.0) #1 SMP PREEMPT_DYNAMIC Mon, 24 Jul 2023 20:19:38 +0000[4.2.] Kernel .config file: Cannot obtain
[5.] Most recent kernel version which did not have the bug: 6.2.9 or more recent?
[6.] Output of Oops.. message (if applicable) with symbolic information resolved (see Documentation/admin-guide/bug-hunting.rst) N/A
[7.] A small shell script or example program which triggers the problem (if possible)
# ethtool -s [INTERFACE] speed 1000

Relevant logs after running `ethtool -s enp6s0 speed 1000`:
juil. 25 21:14:56 kkiotarch NetworkManager[459]: <info> [1690312496.0963] device (enp6s0): carrier: link connected

[X.] Other notes, patches, fixes, workarounds:
As a temporary solution, I have forced port speed to be set at 1000 Mbps via my router.
Apologies if this should have submitted to my distribution's bug report first (Arch Linux); on my current kernel version, there should be no patches applied here compared to upstream.
Thank you,

I would suspect "link speed" is a consequent problem here. Please, check
your setup. Why does disconnection happen again and again? Any problems
with the PCIe link? (caused by reset adapter)
I recommend you contact the platform's vendor support.

rather auto negotiated to 1G (force speed is n/a for 1G/2.5G). This
won't resolve disconnetions.

IMHO, we shall use the advertise command instead of speed command
since we are using legacy advertise setting.
Could you try with below command and see if the link activity happen
accordingly?
Ex:
ethtool -s <interface> advertise <value>
<value> - : 2 (10Mbps)
: 8 (100Mbps)
: 32 (1000Mbps)

Hi,
I ran the command `ethtool -s enp6s0 advertise 0x020` which corresponds to "1000baseT Full", and it indeed works just fine. Interface quickly adopts the 1 Gbps speed. This seems to be a better command to use than "ethtool -s speed". Thanks!
