Duplicate RTM_NEWADDR notifications aren't a problem though, right? The current code send RTM_NEWADDR every time an RA increases the lifetime of an address, so I think it's reasonable to assume that apps have to be able to deal with it, because it's pretty frequent. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
