Read the docs, there are two issues: 1. You need to rebuild libpcap since rpcap is a security problem, it is not enabled by default. Tcpdump et al will not support rpcap without rebuild. 2. The rpcap-protocol.h file is not exported by libpcap and considered internal. The original is too damn messy to use in DPDK as a copy.
