Thanks davide for the good explanation (and the link the the old email I forgot about) > tl;dr: sta2x11 support can be removed. Confirmed. The point here is that we talked with the vendor. They are still using the device (with some extra internal patches), but new development at kernel level is stopped. Since the device is not currently available to the general public, it's ok to save the maintaining efforts. I can submit patch[es] next week or ack removal if somebody submits them earlier. thanks /alessandro
