Browse Source

to support different threshold packet size value other than default
128 bytes.

unsigned integer. It is possible to use **mode_param** initialization
parameter to achieve the same purpose. For example:
... --vdev "crypto_scheduler,mode=packet-size-distr,mode_param=threshold:512" ...
The above parameter will overwrite the threshold value to 512.
