Currently, zero is a valid value for a set action, but it is up to interpretation weather the switch should send the packet to the controller when the ttl is set to zero (as is the case for dec ttl action. It might make sense to change the behavior to return an invalid value error for the set TTL actions, as there should be no reason for a controller to set a TTL to zero?
