When we switched the touchpad to the raw mode, we also disable such firmware gesture and some users may rely on it. Unfortunately, 3 finger swipes are still not supported in most of the Linux environments, which means that we disabled a feature of the touchpad. Allow users to revert the raw reporting mode and keep going with the firmware gestures by providing a new module parameter.
