Randy Dunlap said the following on 2008-12-29 12:36:

drivers/built-in.o: In function `addr_resolve_remote':
addr.c:(.text+0x12fe75): undefined reference to `ip6_route_output'
drivers/built-in.o: In function `rdma_translate_ip':
(.text+0x1301a7): undefined reference to `ipv6_chk_addr'
drivers/built-in.o: In function `rdma_resolve_ip':
(.text+0x1303a9): undefined reference to `ipv6_chk_addr'
drivers/built-in.o: In function `rdma_resolve_ip':
(.text+0x13051b): undefined reference to `ip6_route_output'

when CONFIG_IPV6=n.

Aleksey added IPv6 function to it but not change the Kconfig file.
The following patch will temporarily fix this build failure.
But IMHO separating the IPv4/IPv6 parts or using #ifdef would be better.
