-/**
- * @file
- * RTE mbuf offload
- *
- * The rte_mbuf_offload library provides the ability to specify a device generic
- * off-load operation independent of the current Rx/Tx Ethernet offloads
- * supported within the rte_mbuf structure, and add supports for multiple
- * off-load operations and offload device types.
- *
- * The rte_mbuf_offload specifies the particular off-load operation type, such
- * as a crypto operation, and provides a container for the operations
- * parameter's inside the op union. These parameters are then used by the
- * device which supports that operation to perform the specified offload.
- *
- * This library provides an API to create pre-allocated mempool of offload
- * operations, with supporting allocate and free functions. It also provides
- * APIs for attaching an offload to a mbuf, as well as an API to retrieve a
- * specified offload type from an mbuf offload chain.
- *
- * @warning
- * @b EXPERIMENTAL: this API may change without prior notice
