I should probably fold 6+7 together anyway, so this was my fault.  I
think I was originally keeping them separate because the venet was
serving as the canonical example for the vbus interface.  But Ill just
come up with something simpler to demonstrate the interface and merge
these two patches.

Ack.  Will do.
