This doesn't make a lot of sense to me IPV4 is not a requirement for
batman-adv. Only very specific features will require symbols from IPv4:

* CONFIG_BATMAN_ADV_BLA

   - arp_create

* CONFIG_BATMAN_ADV_DAT

   - arp_create

* CONFIG_BATMAN_ADV_MCAST

   - ip_mc_check_igmp


Basically things which currently depend on INET in net/batman-adv/Kconfig

Or am I missing something here?

Yes, you are right. I must re-check all the symbols again. So thank you!
