------------------ From: Hangbin Liu <[email protected]> [ Upstream commit d23c4b6336ef30898dcdff351f21e633e7a64930 ] Commit 6edb3c96a5f02 ("net/ipv6: Defer initialization of dst to data path") forgot to handle anycast route and init anycast rt->dst.input to ip6_forward. Fix it by setting anycast rt->dst.input back to ip6_input.
