The new packet framework in DPDK 1.7 is one candidate (set of) API's that could be included in ODP (or ported to run on top of ODP). Inclusion in ODP would allow platform specific implementations to offload more of the processing to any suitable hardware. But just having a generic port to ODP could be interesting.
DPDK also have IPv4 and IPv6 longest prefix match which are useful utility functions.
