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?
Regards,
Sven
