I think one of the most important questions that we have to ask
ourselves at some point is if we wanna put ATT into the kernel.

The potential candidate that forces us to think about this is HID over
Low Energy. However I like to see numbers on how the context switches
with keeping ATT in userspace will effect our latency.

I still fail to see how ATT handling in kernel would reduce context
switches. A GATT operation is composed of one or more (possibly many,
see e.g. discovery procedures) ATT PDUs.

Unless you are proposing GATT on kernel as well?
