Created attachment 472267 [details] patch for 5.6 Outgoing multicast packets get reinserted into local processing as if they are received from the network. The machine thus sees its own NA and fills the logs with error messages. This patch removes the message if NA has been generated locally. http://lkml.org/lkml/2008/12/8/146
The attached patch is same as lkml patch. It applies cleanly to 235.
