I hope there is some other reason/benefit besides getting rid of a 
three-line custom struct definition. It may be a trivial 
s/addr_bytes/ether_addr_octet/ change but it touches a lot of places all 
over the DPDK codebase alone, and for 3rd party developers such (at 
least seemingly) gratuitous renames are really irritating.
