*
* A consumer application face is built upon an ip face and identify a local
* consumer application (co-located with the forwarder) that acts as a
* consumer. The interface used by the consumer application face is
* assumed to be reserved only for hICN traffic (e.g., dedicated memif that
* connects the applictation to the forwarder). Only one application face can
* be assigned to an interface.
*
* In the vlib graph a consumer application face directly connect the
* device-input node to the hicn-vface-ip node.
