I can confirm the compile failure in case BR2_PACKAGE_BATMAN_ADV_BATMAN_V is
not enabled...., but the buildroot config still states it is 'exerpimental':


	config BR2_PACKAGE_BATMAN_ADV_BATMAN_V
        	bool "enable B.A.T.M.A.N. V protocol (experimental)"

According to [1] CONFIG_BATMAN_ADV_BATMAN_V option is enabled by default
since 2018.2 (and it seems compile without is not tested very carefully),
maybe time to drop the buildroot config option and always enable
CONFIG_BATMAN_ADV_BATMAN_V?

But will take a deeper look at the source code if the failure is fixable
(or post an upstream failure report)...

Regards,
Peter
