nvme in-band authentication blktests - nvme/043

[alan.adamson]

I'm playing around with in-band authentication and using blktests to see 
how to setup it up and use it.  In test nvme/043, a valid hostkey is 
never initialized and a NULL is being used to setup the target and to 
connect.  Is this expected?  The test with the NULL hostkey passes.  I 
updated the test to use a valid key and it also passes.


diff --git a/tests/nvme/043 b/tests/nvme/043

         truncate -s "${nvme_img_size}" "${file_path}"

Alan's question looks valid for me.

Hannes, may I ask your comment?
