That's true for all Intel controllers going forward, but this is actually an older controller that pre-dates NOIOB. It's the exact same as the 8086:0A54 model, but a particular vendor decided their rebranded device needs to be made special with a different DID. We all agree that's a terrible way to go about this for mutliple reasons, but we can't go back in time to tell the decision makers of this folly. So I think we need to let this last one go through with the quirk. Acked-by: Keith Busch <keith.busch@intel.com>
