+Description: mi: endian fixes
+ We have a couple of endian issues in the mi code: one where we're not
+ converting cdw0 for MI commands, and one where we're using the wrong
+ byte length for an existing conversion. There is also an error in the
+ test suite, where we should be converting the nsze field of a
+ nvme_id_ns.
+ .
+ This change fixes those, so that the test suite passes on a BE platform
+ (ppc64 in my case).
