- * @param node  vlib_node_runtime_t data for this node.
- * @param frame vlib_frame_t whose contents should be dispatched.
- *
- * @par Graph mechanics: buffer metadata, next index usage
- *
- * <em>Uses:</em>
- * - <code>vnet_buffer(b)->ip.save_rewrite_length</code>
- *     - tells the node the length of the rewrite which was applied in
- *       ip4/6_rewrite_inline, allows the code to find the IP header without
- *       having to parse L2 headers, or make stupid assumptions about their
- *       length.
- * - <code>vnet_buffer(b)->flags & VLIB_BUFFER_FLOW_REPORT</code>
- *     - Used to suppress flow record generation for flow record packets.
- *
- * <em>Sets:</em>
- * - <code>vnet_buffer(b)->flags & VLIB_BUFFER_FLOW_REPORT</code>
- *     - To suppress flow record generation for flow record packets
- *
- * <em>Next Index:</em>
- * - Next configured output feature on the interface, usually
- *   "interface-output." Generated flow records head for ip4-lookup

- * @brief IPFIX ipv4 flow-per-packet graph node

- * This is the IPFIX flow-record-per-packet node.

- * @param node  vlib_node_runtime_t data for this node.
- * @param frame vlib_frame_t whose contents should be dispatched.
- *
- * @par Graph mechanics: buffer metadata, next index usage
- *
- * <em>Uses:</em>
- * - <code>vnet_buffer(b)->ip.save_rewrite_length</code>
- *     - tells the node the length of the rewrite which was applied in
- *       ip4/6_rewrite_inline, allows the code to find the IP header without
- *       having to parse L2 headers, or make stupid assumptions about their
- *       length.
- * - <code>vnet_buffer(b)->flags & VLIB_BUFFER_FLOW_REPORT</code>
- *     - Used to suppress flow record generation for flow record packets.
- *
- * <em>Sets:</em>
- * - <code>vnet_buffer(b)->flags & VLIB_BUFFER_FLOW_REPORT</code>
- *     - To suppress flow record generation for flow record packets
- *
- * <em>Next Index:</em>
- * - Next configured output feature on the interface, usually
- *   "interface-output." Generated flow records head for ip4-lookup
