- * Main packet processing function.
- * 64 packet bit mask are used to identify which packets to forward.
- * Performs the following:
- *  - Burst lookup packets in the IPv4 ACL Rule Table.
- *  - Burst lookup packets in the IPv6 ACL Rule Table.
- *  - Lookup Action Table, perform actions.
- *  - Burst lookup Connection Tracking, if enabled.
- *  - Lookup MAC address.
- *  - Set bit mask.
- *  - Packets with bit mask set are forwarded
- *
- * @param p
- *  A pointer to the pipeline.
- * @param pkts
- *  A pointer to a burst of packets.
- * @param n_pkts
- *  Number of packets to process.
- * @param arg
- *  A pointer to pipeline specific data.
- *
- * @return
- *  0 on success, negative on error.
