> 
> Also, refactor the existing implementation to make the code more modular.
> Introduce new generic functions for sending VC messages consisting of
> chunks, in order to isolate the sending algorithm and its implementation for
> specific VC messages.
> 
> Finally, rewrite the function for mapping queues to q_vectors using the new
> modular approach to avoid copying the code that implements the VC
> message sending algorithm.
