Does 8-Stream support Intel i225 Ethernet controler by now?

Post by rebakker » 2022/08/25 09:06:36

I'm mainly a Linux user, and I'm planning to perform a clean install of CentOS Stream 8 (the latest download) on a system with a 11th generation Intel i5 and an I225LM/I225IT Ethernet controller. Especially the I225 seems to have been a problem. Has this been solved within the latest installation package of CentOS Stream 8? Or can you provide a list of instructions and links to get this up and running?

Kind regards,

As no forum answers were provided, I needed to test it. I've used a Kontron COMe-bTL6 board which has the i225-LM.
I have performed some research regarding the i225-LM support under 8-Stream. As 8-Stream is the upstream release for RHEL8, so when the i225 is supported by RHEL8 it is probably also supported by CentOS Stream 8. And I found the following Hardware for Linux test result which supports this:
And so I installed the CentOS-Stream-8-x86_64-20220816-dvd1.iso on the COMe-bTL6.

lshw shows the following:

Code: Select all

description: Ethernet interface
product: Ethernet Controller I225-LM
vendor: Intel Corporation
physical id: 0
bus info: pci@0000:23:00.0
logical name: enp35s0
version: 03
serial: 00:e0:4b:75:68:eb
size: 1Gbit/s
capacity: 1Gbit/s
width: 32 bits
clock: 33MHz
capabilities: pm msi msix pciexpress bus_master cap_list rom ethernet physical 10bt 10bt-fd 100bt 100bt-fd 1000bt-fd autonegotiation
configuration: autonegotiation=on broadcast=yes driver=igc driverversion=4.18.0-408.el8.x86_64 duplex=full firmware=1079:8770 ip= latency=0 link=yes multicast=yes port=twisted pair speed=1Gbit/s
resources: irq:19 memory:80500000-805fffff memory:80600000-80603fff memory:80400000-804fffff
So the igc driver with version 4.18.0-408.el8.x86_64 supports the i225-LM.
And when performing a speedtest this resulted in a 920.59Mbps download and a 932.16Mbsp upload speed. So no delay problems for this 1Gbit/s link.
