+ slave and the secondary slave, and distributes the enqueued crypto
+ operations to them based on their data lengths. A crypto operation will be
+ distributed to the primary slave if its data length is equal to or bigger
+ than the designated threshold, otherwise it will be handled by the secondary
+ slave.
+
+ A typical usecase in this mode is with the QAT cryptodev as the primary and
+ a software cryptodev as the secondary slave. This may help applications to
+ process additional crypto workload than what the QAT cryptodev can handle on
+ its own, by making use of the available CPU cycles to deal with smaller
+ crypto workloads.
