[...] This reminds me of an discussion I had with a user who tried the = autorate-ingress feature unsuccessfully, it sems he would have needed an = additional toggle to set the lower range for the bandwidth as due to = some quirkiness his ingress did not as much get autorated but rather = throttled.
