- * Configure a port for internal and/or external loopback. Internal loopback
- * causes packets sent by the port to be received by Octeon. External loopback
- * causes packets received from the wire to sent out again.
- *
- * @ipd_port: IPD/PKO port to loopback.
- * @enable_internal:
- *		   Non zero if you want internal loopback
- * @enable_external:
- *		   Non zero if you want external loopback
- *
- * Returns Zero on success, negative on failure.
