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.

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. -- MST --------------------------------------------------------------------- To unsubscribe, e-mail: virtio-dev-unsubscribe@lists.oasis-open.org For additional commands, e-mail: virtio-dev-help@lists.oasis-open.org
