--- Comment #1 from Conrad Meyer <cem at freebsd.org> ---
It's sort of important to define which hardware models our driver supports,
because it isn't all of them.  I think there are historical devices called QAT
with a different programming model that we do not support.  (Maybe I'm
mistaken; I'm sure Mark is more familiar.)

>From the OS perspective, qat is a generic PCIe device.  Sometimes it is part of
a SoC, but I believe Intel has also produced installable PCIe board versions. 
(I don't know if our driver supports those models or not.)  I don't think it is
enumerated in CPU feature flags (dmesg), even on SoC models.

Leaving it to Mark but IMO this is NOTABUG.
