Hi Andrew,
We're currently working on re-factoring our driver onto the framework.
I will make sure we can give you a feedback ASAP.

We're also trying to asses the performance difference between what we have now and what we can achieve after re-factorng.

Thanks,
Piergiorgio

Agreed. Lets focus on what we have now.

https://urldefense.com/v3/__https://patchwork.kernel.org/project/netdevbpf/patch/20240418125648.372526-2-Parthiban.Veerasooran@microchip.com/__;!!KkVubWw!n9QOIA72sKA9z72UFogHeBRnA8Hse9gmIqzNv27f7Tc-4dYH1KA__DfMSmln-uBotO-bnw3PC2qXbfRn$

Version 4 failed to apply. So we are missing all the CI tests. We need a v5 which cleanly applies to net-next in order for those tests to run.

I think we should disable vendor interrupts by default, since we currently have no way to handle them.

I had a quick look at the comments on the patches. I don't think we have any other big issues not agreed on. So please post a v5 with them all addressed and we will see what the CI says.

Piergiorgio, if you have any real problems getting basic support for your device working with this framework, now would be a good time to raise the problems.

        Andrew
