Some architectures (ex: Power8) have a cache line size of 128 bytes, so the drivers should not expect that prefetching the second part of the mbuf with rte_prefetch0(&m->cacheline1) is valid. This commit add helpers that can be used by drivers to prefetch the rx or tx part of the mbuf, whatever the cache line size.
