Agreed... I've been thinking about it some more, and now that I know
about struct class_interface, I actually don't see a need to create a
virtual bus with virtual devices.

I think it should work just to create an "infiniband" class, and have
IPoIB et al register class_interfaces for this class.  Then low-level
drivers will register class_devices in the infiniband class so IPoIB
etc. get notified when devices show up or leave.  IPoIB etc can create
their own class_devices (in their own class).

Hierarchical classes might make it neater but it all seems to work in
my head....
