If more features needs to be added, another feature arc can be cre- ated In fast path, rte_graph_feature_arc_t can be translated to (struct rte_graph_feature_arc *) via rte_graph_feature_arc_get(). Later is needed to add as an input argument to all fast path feature arc APIs Definition at line 84 of file rte_graph_feature_arc_worker.h.
