I love naming discussions :-)

+1 to separate namespaces for low-level DPDK wraps, and more rustic
higher-level APIs. However, that doesn't mean that the names get to be
ugly! Let's definitely remove the "lib" in dpdklib (or libdpdk), and the
"rte_" prefix from libs.

How about having "dpdk::raw::*" e.g. "dpdk::raw::ethdev" for low-level
wraps and "dpdk::*" e.g. "dpdk::ethdev" for higher level apis?
