/**
 * @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).
