Obviously that was very old, along with all the other software and OS on the machine.  I've now upgraded everything.

This worked, but only until I rebooted the computer.  Now I can't for the life of me get ZFS to use the QAT anymore, and he hasn't been able to either for over a year it seems.  You might see our lengthy discussions on the ZoL Github pages.

It seems that nobody here has access to Intel's QAT hardware, so I'm
afraid it's hard to get help. But in case you find the solution, it's
welcomed to contribute back.
