This is wrong. nawun comes right after dlfeat

And here the error cancels out since here there should be 'nacwu' field.

Not related to the patch, but maybe rename this to rsvd192 for the sake of
consistency?

I reviewed this patch by cross referencing the nvme structures as defined in
the kernel,
and the spec.
I prefer to merge this patch with all other spec updates you do in following
patches,
to bring nvme.h up to date to 1.3d,
so that it will be easier to review this and remove some noise from other
patches.
Best regards,
Maxim Levitsky
