Just in case someone it wondering why this wasn't applied yet. Antonio didn't
like the patches and thus the patches were assigned to him in Patchwork [1].
It is currently unknown what problems he meant, but he created a branch under
his namespace [2]. This branch only contains a re-factorization of the first
patch (+ batadv_bla_check_claim/batadv_bla_is_my_claim behavior changes when
batadv_primary_if_get_selected or batadv_claim_hash_find return NULL). We
currently don't know whether this all or if he had more problems with these
patches.

It is therefore currently unknown how to continue from here. Antonio, please
provide a statement what we should do with the patches.

We don't want to add new patches before the v2017.0 release but maybe this is
a candidate for v2017.1.

Kind regards,
Sven
