net: sched: act_tunnel_key: request UDP checksum by default
There's currently no way to request (outer) UDP checksum with
act_tunnel_key. 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.
