[PATCH 3/3] nvmet: include all configured ports in discovery log page for unique discover controller

[Christoph Hellwig]

So maybe we'll take a step and think about what we actually want
to support.  Here is my understanding, which might as well be incorrect
and/or incomplete.

 1) support a uniqueue discovery controller for bidirectional
    authentication to work properly

The only thing we really need is to have the existing discovery log for
the well known discovery subsystems to be able to also show up as a
unique discovery subsystem.  Either by just renaming it like your earlier
patch did, or by supporting an alternative name in addition to that.

 2) (optionally) make the well known discovery controller go away

Just renaming the subsystem will make the well known one go away,
but while that can be useful for some use cases, I think making it
always go away has the potential for breakage.  So maybe we need
to not rename but be able to create an alias and have a way to
disable the well known discovery controller if not used.

 3) Actually have a different content.

Can you explain the use cases here a bit more?

And maybe add anything else we'd like to consider.  (Everyone else
on the list please also chime in)
