The same problem in STABLE...
from revision 1.85.2.15 of net/if.c:
#ifdef INET
/*
* Also send gratuitous ARPs to notify other nodes about
* the address change.
*/
TAILQ_FOREACH(ifa, &ifp->if_addrhead, ifa_link) {
if (ifa->ifa_addr != NULL &&
ifa->ifa_addr->sa_family == AF_INET)
arp_ifinit((struct arpcom *)ifp, ifa);
}
#endif
arp_ifinit defined in netinet/if_ether.c
This makes 'device ether' mandatory for 'options INET',
so kernel with 'options INET', but without 'device ether'
failed to built:
