I did not look at the pktgen code, but directly accessing mbuf field dynfieldX is likely a bug. pktgen should register a dynfield for its own usage to avoid conflicts with other parts of the dpdk. Example of such a conversion to the new mechanism: https://git.dpdk.org/dpdk/commit/?id=eb8258402b3f -- David Marchand
