Detailed Description

       Warning
           EXPERIMENTAL: All functions in this file may be changed or removed without prior notice.

       This API allows to do control path functions of ip4_* nodes like ip4_lookup, ip4_rewrite.

Function Documentation

   int  rte_node_ip4_route_add  (uint32_t  ip,  uint8_t  depth, uint16_t next_hop, enum rte_node_ip4_lookup_next
       next_node)
       Add ipv4 route to lookup table.

       Parameters
           ip IP address of route to be added.
           depth Depth of the rule to be added.
           next_hop Next hop id of the rule result to be added.
           next_node Next node to redirect traffic to.

       Returns
           0 on success, negative otherwise.

   int rte_node_ip4_rewrite_add (uint16_t  next_hop,  uint8_t  *  rewrite_data,  uint8_t  rewrite_len,  uint16_t
       dst_port)
       Add a next hop's rewrite data.

       Parameters
           next_hop Next hop id to add rewrite data to.
           rewrite_data Rewrite data.
           rewrite_len Length of rewrite data.
           dst_port Destination port to redirect traffic to.

       Returns
           0 on success, negative otherwise.

   __rte_experimental  int rte_node_ip4_reassembly_configure (struct rte_node_ip4_reassembly_cfg * cfg, uint16_t
       cnt)
       Add reassembly node configuration data.

       Parameters
           cfg Pointer to the configuration structure.
           cnt Number of configuration structures passed.

       Returns
           0 on success, negative otherwise.
