Netlink is supposed to be encoded as Type-Length-Value and correctly written
programs ignore types they don't understand. So either the library is getting
confused by the type or the attribute is not encoded correctly.


The issue could be in libnetlink library. What version of collectd and libnetlink
are you using?
