Currently, the tunnel_key tc action does not set TUNNEL_CSUM, thus transmitting packets with zero UDP checksum. This is inconsistent with how we treat non-lwt UDP tunnels where the default is to fill in the UDP checksum. Non-zero UDP checksum is the better default anyway for various reasons previously discussed.
Make this configurable for the tunnel_key tc action with the default being non-zero checksum. Saves a lot of surprises especially with IPv6.
