40 * RTE Cryptodev Scheduler Device
42 * The RTE Cryptodev Scheduler Device allows the aggregation of multiple (slave)
43 * Cryptodevs into a single logical crypto device, and the scheduling the
44 * crypto operations to the slaves based on the mode of the specified mode of
45 * operation specified and supported. This implementation supports 3 modes of
46 * operation: round robin, packet-size based, and fail-over.
