Please fix the existing driver instead of adding a new one. A patch was submitted for this device some time ago but there was never any follow-up after the first round of review process: https://marc.info/?t=151707061600004&r=1&w=2 You could use that patch as a starting point. But please note that it's unclear whether some or all of these changes were copied from GPL code. It would be better to base such changes on the FreeBSD driver which seems to support this device as well. > Could you be so kind to answer: > > 1.
