Implement functionality to receive and forward a new TVLV capable multicast packet type. The new batman-adv multicast packet type allows to contain several originator destination addresses within a TVLV. Routers on the way will potentially split the batman-adv multicast packet and adjust its tracker TVLV contents. Routing decisions are still based on the selected BATMAN IV or BATMAN V routing algorithm. So this new batman-adv multicast packet type retains the same loop-free properties. Also a new OGM multicast TVLV flag is introduced to signal to other nodes that we are capable of handling a batman-adv multicast packet and multicast tracker TVLV. And that all of our hard interfaces have an MTU of at least 1280 bytes (IPv6 minimum MTU), as a simple solution for now to avoid MTU issues while forwarding.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
