Well not really. It's over admin commands. When these were built the
intent always was that it's possible to use admin commands through
another interface, other than admin queue. Is there a problem
implementing admin commands over a memory BAR? For example, I can see
an "admin command" capability pointing at a BAR where
commands are supplied, and using a new group type referring to
device itself.
