Building on an Alpine Linux host running the current -lts kernel which is 6.1.30, logs attached. Basically a change of prototype of the netif_napi_add() function. The stub driver from the kernel has never worked properly on my adapter (an I350, quad ports). Is Intel working on this?

Hello @m4t,
Thank you for posting in Intel Ethernet Communities.
I am sorry you are having issues with your Intel Ethernet Server Adapter I350, I will be glad to assist.
In order to investigate further about this, please provide a system report by running the Intel® System Support Utility for Linux (https://www.intel.com/content/www/us/en/download/18895/26735/intel-system-support-utility-for-the-linux-operating-system.html?).
Looking forward to your response.
Best regards,

Hi @B_Y, thank for picking this up!
Just to clarify: I'm not having issues with the adapter itself. I am currently running it with the igb-5.13.16 driver from Intel on Linux 5.15 with no problem. The driver from the vanilla Linux kernel does not work though (I forgot what the errors were) but since I switched to the Intel driver the adapter works perfectly fine.
My problem is that the latest Intel igb driver does not build with more recent Linux kernels, e.g. the 6.1 branch. The issue has to do with a change in the NAPI driver model where the weight argument has been dropped. I attached the build logs to the previous post but here's the compiler error:

I'd contribute a patch but I doubt this is an open-source project, at least I haven't found the official repo anywhere.

Hello @m4t,
Thank you for your feedback.
We need your assistance in providing the precise Ethernet model: I350 (Eg command: lspci | grep -i Ethernet).

Hello @B_Y ,
Sorry but the details of the adapter are completely irrelevant to the problem at hands. The adapter is fine. The problem is about compiling the igb driver. Coincidence or not, I just noticed that Intel did fix the driver and published it on sourceforge. Interestingly enough Intel's official driver page still points at the old version.

Hello @m4t,
Thank you for your respond.
In the event that we need to seek out additional guidance, we needed your assistance in confirming the Ethernet model: I350.
SourceForge focuses mainly on software deployment; it offers the most recent fixes and lets developers mail in their suggestions.
It was published with a generic driver to allow universal features on Intel's public page.
Please let me know if I can be of any assistance.
Best regards,
