"police" refers to the policing component of the traffic control
subsystem in the kernel.
"bucket" (with the "conform" and "count" operators) is an
abstracted single bucket. If you actually use it, and you're
generating "tc" output, tcc will express its function in terms
of "police".
SLB, DLB, etc. are basically expressions that use buckets. Again,
tcc will (try to *) express them using "police", plus some
classification tricks.
(*) Buckets can be used for arbitrary constructs that exceed what
can be done with the policing mechanisms of kernel traffic
control. The "dictionary tcc uses is in tcc/if_u32.c:map
Think of it as "police" being a pocket calculator, "bucket" being
the basic arithmetic operations, and SLB, etc. being some common
formulas, like the compound interest formula. If presented with
such a formula, tcc will then know which buttons to press on the
pocket calculator.
