I thought the whole point of class_devices and class_interfaces
in the driver model was to bind devices to drivers.

One difference to PCI analogy is IPoIB is "creating" the virtual device
when it talks to the IB HCA driver and sets up the various queues.
I don't know details of which types of queues are necessary for one
IPoIB instance.  But it seems natural for an IPoIB "device" to have
it's own set of queues for RX/TX and any admin stuff.

Looks good to me - thanks!
