I get the point of this change: It tests the performance of copying raw memory objects using respectively rte_memcpy and DMA, without the mbuf indirection overhead.

However, I still consider the existing test relevant: The performance of copying packets using respectively rte_memcpy and DMA.

So, instead of replacing mbufs with mempool objects, please add new test variants using mempool objects.
