The relative performance numbers was only tested with OvS/DPDK, I did not test 
on OvS alone. Each action was tested individually, using a single PMD thread 
and a single flow like such $ ovs-ofctl add-flow br0 
'in_port=1,ip,actions=mod_nw_ttl:254,output=2'.  All other AVX components were 
disabled (DPCLS,MFEX,etc.) and traffic was sent at 100% line rate.
