> The function rte_pktmbuf_init() expects that the mempool private area is
> large enough and was previously initialized by rte_pktmbuf_pool_init(),
> which is not the case.
>
> This causes the function rte_pktmbuf_priv_size() to return an
> unpredictable value, and this value is used as a size in a memset.
>
> Replace the mempool object initializer by my_obj_init(), which does not
> have this constraint, and fits the needs for this test.
