Technically, nothing.
But as I'll be looking into tcp in-band _encryption_ as the next step I 
found it logical to have a disinct directory.
Especially as I still fail to see the actual use-case for using in-band 
authentication _without_ encryption.

We could rename it to nvmeof-auth, though.

Especially as there's the nvmeof-mp precedent, which also has a separate 
directory.

Essentially, yes.
And I'd be happy to merge them, like having a common nvme rc
file to be used for all nvme related tests.

Cheers,
