From: Suzuki K Poulose <[email protected]> If a graph node is not found for a given node, of_get_next_endpoint() will emit the following error message :
OF: graph: no port node found in /<node_name> If the given component doesn't have any explicit connections (e.g, ETE) we could simply ignore the graph parsing.
