You can use this patch as a base. It needs a bit more work
(for example the CONFIG_NET_SCHED_ESTIMATOR ifdefs are
unnecessary, but I've added them to remind me to clean this
up in all schedulers), but it works well enough for testing.

Actually .. do you still need your changes with this patch?
You can now replace the default estimator by one with a
shorter interval.
