I’ll carry that suggestion back to the development team, it seems like a good idea to me and would have saved us some time.

It would be very helpful to update the driver so that only supported hashing configurations are accepted.

Intel has received requests from other parties requesting support for the configuration you’re attempting and the request is under consideration but at this time we can’t make any commitment as to when that sort of support might be available.
