* Implements the input and output iface nodes. Input iface nodes
* process incoming interests while output face nodes process outgoing
* data packets.
*
* Input iface nodes follow ip-lookup nodes and their purpose
* is to create (or retrieve if already existing) the list incoming face
* for each the interest packet.
* The following node to the input iface nodes is the hicn-interest-pcslookup.
* Output iface nodes follow the hicn-data-fwd and the hicn-interest-hitcs
* nodes and they perform the dst nat on each data packet. The node following
* the output face nodes depends on the adjacency type. In case of ip, the
* following node is the ip4/6-lookup, in case of tunnels the next node is the
* one implementing the tunnel encapsulation (udp-encap, mpls, etc).
