commit 71130f29979c7c7956b040673e6b9d5643003176 upstream.
Before ip_tunnel_ecn_encap() and udp_tunnel_xmit_skb() we should filter tos value by RT_TOS() instead of using config tos directly.
vxlan_get_route() would filter the tos to fl4.flowi4_tos but we didn't return it back, as geneve_get_v4_rt() did. So we have to use RT_TOS() directly in function ip_tunnel_ecn_encap().
