[PATCH 06/16] batman-adv: Provide TTVN in the mesh_info netlink msg

[Simon Wunderlich <sw-2YrNx6rUIHYiY0qSoAWiAoQuADTiUCJX@public.gmane.org>]

From: Sven Eckelmann <sven-KaDOiPu9UxWEi8DpZVb4nw@public.gmane.org>

The TTVN is the main information for the debugging of translation table
problems. It is therefore necessary when comparing the global translation
tables.
