I do not think this is ddbridge. The bridge as I know is a 1 year newer card. The ngene18 driver is used for my card as I know.
I‘m only aware that the vendor of the chip on my card has discontinued further development. The vendor also do no longer provide updated and support to dd. However this does not mean the card / driver itself no longer works. It just do not get new features.
The continuity errors are caused by something different and have been introduced after 7.90.10.
