Detailed Description

RTE Cryptodev Scheduler Device

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