The following two patches fix critical bugs with the counter tracking the number of nodes with no multicast optimizations support.
Mesh networks from batman-adv version 2014.2.0 or later are potentially affected and might kill kittens (or at least kills downloads of cat pictures you try to do over IPv6).
