The comments for the function prototype can be polished to make it clearer.
Also the formatting shall be inline with the rest of dpdk code. Such as

/**
 * <brief introduction to the function prototype>
 *
 * @param x
 *   Description to the param x.
 * @return
 *   - 0 if the crypto request is built successfully.
*    - error code otherwise.

The above function prototype worth some description too?

I assume the functions refactor_xxx() is removed in future patches right?
Maybe adding some comments to help reviewing.

Same as above, some comments would be helpful and shall remove altogether in
later patches.
