This is problem especially for IPv6. Right now, tunnel_key action with IPv6 does not work without going through hassles: both sides have to have udp6zerocsumrx configured on the tunnel interface. This is obviously not a good solution universally. It makes more sense to compute the UDP checksum by default even for IPv4. Just set the default to request the checksum when using act_tunnel_key.
