There is no reason for rte_memcpy to exist, it only exists because the DPDK team at Intel was able to get a faster result for bulk copies than the current glibc versions. Medium term, it would be good to kill rte_memcpy for the fixed size case. Already done for several other architectures. Short term, none of this is urgent.
