We have a problem with an Intel QUAD NIC Intel Corporation 82575GB Gigabit Network Connection (rev 02) used on a Debian system:
Linux lux-athos 6.1.0-18-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.76-1 (2024-02-01) x86_64 GNU/Linux
IGB driver is used for the NIC.

Our problem is the following:
We have a Network Switch connected to the Intel NIC Card.
On our network device, we disable the auto-negotiation. We set then, one at the time, the following speeds on the device:
speed 10 half
speed 10 full
speed 100 half
Expected Results:
For each of the manual speed set on the device, the port on the QUAD should negotiate the correspondent value. It works for speed 10 FX/HX. For speed 100 half, the Intel card will remain in an Unknown state and our device will see the link as down. (L.E: when setting the speed directly to 100 MB from the start, without the 10 speed settings, we will not see any issue)

If we connect the same network device to a similar QUAD, Intel Corporation 82576 Gigabit Network Connection (rev 01), there is no issue.
However, in this case we use an older Linux Kernel: Linux lux-sqa 4.19.0-5-amd64 #1 SMP Debian 4.19.37-3 (2019-05-15) x86_64 GNU/Linux

Can this be a kernel issue or it is a NIC problem? Please advice in solving this situation
