This is a debugging feature that is not really needed in production kernels, so we prefer to allow it to be removed so we don't waste resources. We're publishing this for a few reasons: 1. it will help prevent rebasing mistakes when sending patches upstream from our internal tree, because a lot of this code is spread around the driver; 2. in some occasions, we may ask advanced users to enable it so we can get more data and run more tests in case of tricky bugs; 3. for the specific case of twt_setup, this allows running some TWT test scenarios with our driver that wouldn't be easily available otherwise. Is it okay to keep it? -- Cheers, Luca.
