Avoid possible TX Hangs caused by using long Qbv cycles. In some cases, using long cycles (more than 1 second) can cause transmissions to be blocked for that time. As the TX Hang timeout is close to 1 second, we may need to reduce the cycle time to something more reasonable: the value chosen is 1ms.
