We've enabled the supporte into nvmecli you can pull my branch here:
https://github.com/ScottyBauer/nvme-cli/tree/sed-nvme


Here are some shellscripts I use for testing -- also a HOW-TO-USE in there.

I may have regressed some Single user mode stuff in the library. I was under
the impression one could setup multiple Locking ranges under Single User Mode.
But I can only get one setup without my drive complaining. It doesn't work in
sed-util either, so I have to go read the SUM spec again and see if that is
actually a use-case that's possible or if I was dreaming this test up. I swore
I had this working on previous iterations, but I could be wrong. Normal mode
seems to work fine, though.
