Subject: [PATCH net-next 0/3] taprio queueMaxSDU fixes

This fixes 3 issues noticed while attempting to reoffload the
dynamically calculated queueMaxSDU values. These are:
- Dynamic queueMaxSDU is not calculated correctly due to a lost patch
- Dynamically calculated queueMaxSDU needs to be clamped on the low end
- Dynamically calculated queueMaxSDU needs to be clamped on the high end

Vladimir Oltean (3):
  net/sched: taprio: fix calculation of maximum gate durations
  net/sched: taprio: don't allow dynamic max_sdu to go negative after
    stab adjustment
  net/sched: taprio: dynamic max_sdu larger than the max_mtu is
    unlimited
