Please don't top post.
The naming issue is that almost all libraries in DPDK start with rte_ prefix
and the testpmd functions do not.
The flow_classify example is pretty much abandonware at this point.
Code is not updated, other than build breakages.
Last time I looked at it noticed lots of code reinvention useless code,
and only supports IPv4. It really needs a rewrite.
