 * @description
 *      This file contains the main cipher performance sample code. It is
 *      capable of performing all ciphers
 *
 *      This code pre-allocates a number of buffers as defined by
 *      setup->numBuffers. The pre-allocated buffers are then
 *      continuously looped until the numLoops is met.
 *      Time stamping is started prior to the
 *      Operation and is stopped when all callbacks have returned.
 *      The packet size and algorithm to be tested is setup using the
 *      setupCipherTest function. The framework is used to create the threads
 *      which calls functions here to execute cipher performance
