We introduce Scheduler Workqueue\nthen we could directly dispatch streams to another worker core which is\naffinity with a specific node.\n\nThis RFC：\n 1. Introduce core affinity API and graph clone API.\n 2. Introduce key functions to enqueue/dequeue for dispatching streams.\n 3. Enhance rte_graph_walk by cross-core dispatch.\n 4. Add l2fwd-graph example and stats for cross-core dispatching.\n\nWith this patch set, it could easily plan and orchestrate stream on\nmulti-core systems.\n\nFuture work:\n 1. Support to affinity lcore set for one node.\n 2. Use l3fwd-graph instead of l2fwd-graph as example in patch 06.\n 3. Add new parameter, like --node(nodeid, lcoreid) to config node for core\n affinity.\n\nComments and suggestions are welcome.
