Improve dpdk-input node to handle drivers not setting mbuf PTYPE

For drivers that do not provide dpdk rte_mbuf PTYPE information,
check ethernet header Etype to acccelerate IP4 and IP6 forwarding
path. Update packet trace for dpdk-input node to provide more info
from DPDK rte_mbuf offload flags and packet types.
