@Tedd: Do we happen to autopts working with BlueZ for L2CAP tests? Or
perhaps anything that Bastien can use as a reference to test his
changes.
@Batien: We would like to have autopts
(https://github.com/intel/auto-pts) to handle the qualification but
there is still some work pending in order to enable it to work with
L2CAP. Ultimately we could even attempt to integrate autopts on CI to
run it automatically, but in order to do that we need:
1. We need to emulate the PTS dongle (USB emulator?)
2. Run a Windows VM on CI, attach the emulated dongle to it and run
PTS on top (not sure if github actions do allow this)
3. Identify what tests need to run e.g. L2CAP changes should trigger
only L2CAP tests
