No, they/you just haven't compiled network coding for batman-adv. And
you don't need it.

What about the rest mentioned in my other mails?

No. Use a recent version (unless you know that this is a regression).

It just means that kernel 4.4 includes (more or less) batman-adv 2015.2.
You can still use batman-adv 2016.2 as external module for this kernel
version.

Hm? This doesn't make a lot of sense. batman-adv doesn't require special
distribution support. It is just a Linux kernel module. You have to find
out what other things (hw/drivers/tc/iptables/...) are causing the
problems on your system.

And I even know of people that use Arch Linux on their Freifunk supernodes
together with batman-adv.

Kind regards,
Sven
