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?
