  Local or Host destined pkts can be redirected IPv4 local node
using IP4 Lookup node entries with prefix of 32 and be redirected
to this IP4 local node for further processing.

+ip4_local
+~~~~~~~~~
+This node is an intermediate node that does ``packet_type`` lookup for
+the received ipv4 packets and the result determines each packets next node.
+
+On successful ``packet_type`` lookup, for any IPv4 protocol the result
+contains the ``next_node`` id and ``next-hop`` id with which the packet
+needs to be further processed.
+
+On packet_type lookup failure, objects are redirected to ``pkt_drop`` node.
+``rte_node_ip4_route_add()`` is control path API to add ipv4 address with 32 bit
+depth to receive to packets.
+To achieve home run, node use ``rte_node_stream_move()`` as mentioned in above
+sections.
