Early LLQ implementations actually enforced the implicit policer at
all times, even with no congestion. Later they switched it to police
only during congestion, so you need to use an explicit policer if you
wanted to restore that behavior.

The RFC for EF (RFC2598) doesn't specify whether the rate limiter
should apply only during congestion or at all times, as far as I can
see.

I have, at previous jobs, had an SP do the strict policing of EF
traffic on ingress to the purchased rate. In those cases, we used an
explicit policer to mark down overage rather than simply let the SP
drop it.
