+* **CDEV_SCHED_MODE_PKT_SIZE_DISTR:**
+
+ Packet-size based distribution mode, which works with 2 slaves, primary
+ slave and secondary slave, and distribute the enqueued crypto ops to them
+ based on their data lengths. A crypto op will be distributed to the primary
+ slave if its data length equals or bigger than the designated threshold,
+ otherwise it will be handled by the secondary slave.
+
+ A typical usecase of this mode is with QAT cryptodev as primary and a
+ software cryptodev as secondary slave. This may help the application being
+ capable of processing extra crypto workload than what the sole QAT cryptodev
+ can handle, by making use of the available CPU cycles to deal with lesser
+ crypto workloads.
