tc qdisc command is partially broken after applying patch-4.14.76-77.
Applying patch-4.14.77-78 didn't fix it.
Test command:
tc qdisc add dev eth0 root handle 1: hfsc default fffd

I have identified the problematic sub-patch out of patch-4.14.76-77 to
be the problem:
diff --git a/net/sched/sch_api.c b/net/sched/sch_api.c
index 22bc6fc48311..cd69aa067543 100644
Without this small patch the above "tc qdisc" command works like a charm.
Maybe someone can have a look at it.
