Dear Maintainer,
* What led up to the situation?
I installed Debian on a Minisforum UM450 using a 2.5G NIC (Intel I225-V).
Speed autonegociation sometimes set the speed to 1Gbps (on a gigabit network), but more often than not it is set to 100Mbps.
It sometimes oscillates between 100 and 1000, but, most of the time, the speed is 100Mbps.
* What exactly did you do (or not do) that was effective (or
ineffective)?
I tried the kernel version in experimental (6.3.4). It was the same as the one for current bookworm/sid (6.1.27).
I tried to change the cable and switch.
* What was the outcome of this action?
The same behavior.
* What outcome did you expect instead?
Since the I225-V is supposed to work on gigabit networks, whatever the kernel version, I expected it to work OOTB.
