Before anything, could you elaborate a bit on what lead to you wanting this? There are a couple of reasons why merging this in the kernel might be problematic. 1) I don't think we will ever support the full capabilities of the devices, so configuration via userspace apps will always be required, and here we are introducing a weird line between the two. 2) There is already an ecosystem of userspace configuration apps, with which this would conflict. They might not be in the best maintenance state due to lack of time from the maintainers, but moving this functionality to the kernel, which is harder change, and harder to ship to users, will only make that worse. Cheers, Filipe Laíns
