====================
Taprio qdisc fixes

I'm re-sending this series, now with the "net-next" prefix in the subject.

The only change from the previous version is in patch 3. As suggested by Cong
Wang, it removes the !entry check within should_restart_cycle() since it is
already checked by the caller. As a side effect, that function becomes a dummy
wrapper on list_is_last() so we simply remove it and call list_is_last()
instead.
