I'm trying to follow the instructions in ovs-2.5/INSTALL.DPDK.md and am 
getting the following error. This is with dpdk-2.2.0 and Centos 7.1:

                  from lib/netdev-dpdk.c:58:
/third-party/dpdk/x86_64-native-linuxapp-gcc/include/rte_memcpy.h: In 
function ‘rte_memcpy’: /third-party/dpdk/x86_64-native-linuxapp-gcc/include/rte_memcpy.h:625:2: 
warning: implicit declaration of function ‘_mm_alignr_epi8’ 
   MOVEUNALIGNED_LEFT47(dst, src, n, srcofs);

Can anyone please point out if I need to install anything specific or what 
I'm missing?
