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
