tipc: fix compile error when IPV6=m and TIPC=y
When IPV6=m and TIPC=y, below error will appear during building kernel image: net/tipc/udp_media.c:196: undefined reference to `ip6_dst_lookup' make: *** [vmlinux] Error 1 As ip6_dst_lookup() is implemented in IPV6 and IPV6 is compiled as module, ip6_dst_lookup() is not built-in core kernel image. As a result, compiler cannot find 'ip6_dst_lookup' reference while compiling TIPC code into core kernel image. But with the method introduced by commit 5f81bd2e5d80 ("ipv6: export a stub for IPv6 symbols used by vxlan"), we can avoid the compile error through "ipv6_stub" pointer to access ip6_dst_lookup(). Fixes: d0f91938bede ("tipc: add ip/udp media type") Suggested-by: Marcelo Ricardo Leitner <marcelo.leitner@gmail.com> Signed-off-by: Ying Xue <ying.xue@windriver.com> Signed-off-by: David S.
