/**
* @file face_node.h
*
* Implements the input and output face nodes. Input face nodes
* process incoming data while output face nodes process outgoing
* interests packets.
*
* Input face nodes follow hicn-face-input nodes and their purpose
* is to retrieve the list of possible incoming faces for each the data packet.
* The following node to the input face nodes is the hicn-data-pcslookup.
* Output face nodes follow the strategy and the hicn-interest-hitpit nodes and
* they perform the src nat on each interest packet. The node following the
* output face nodes depends on the adjacency type. In case of ip, the following
* node is the ip-rewrite, in case of tunnels the next node is the one implementing
* the tunnel encapsulation (udp-encap, mpls, etc).
