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.
