@ -71,6 +71,11 @@ two calls:
mode parameter values are specified in the "Cryptodev Scheduler Modes
Overview" section.
* mode_param: Specify the mode-specific parameter. Some scheduling modes
may be initialized with specific parameters other than the default ones,
such as the **threshold** packet size of **packet-size-distr** mode. This
parameter fulfills the purpose.
* ordering: Specify the status of the crypto operations ordering feature.
The value of this parameter can be "enable" or "disable". This feature
is disabled by default.
