ipip, sit: fix ipv4_{update_pmtu,redirect} calls
ipv4_{update_pmtu,redirect} were called with tunnel's ifindex (t->dev is a tunnel netdevice). It caused wrong route lookup and failure of pmtu update or redirect. We should use the same ifindex that we use in ip_route_output_* in *tunnel_xmit code. It is t->parms.link . Signed-off-by: Dmitry Popov <ixaphire@qrator.net> Signed-off-by: David S.
