Detailed Description

       rte_graph Feature arc object

       Feature arc object holds control plane and fast path information for all features and all interface index
       information for steering packets across feature nodes

       Within a feature arc, only RTE_GRAPH_FEATURE_MAX_PER_ARC features can be added. If more features needs to
       be added, another feature arc can be created

       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
