Most probably not, though the majority of .shutdown method implementations in sys/netgraph do include a call to NG_NODE_SET_PRIVATE(node, NULL), so I did a C/P from one of those for consistency. If there's a consensus that NG_NODE_SET_PRIVATE(node, NULL) in shutdown methods serves no useful purpose then we should do a sweep across all the existing nodes... Marko
