Token bucket rate limiter
Maturity plannedTargets FPGA + ASICDifficulty EasyPriority 2
Single or dual (committed / peak) token bucket policer and shaper with configurable rate and burst size and color marking.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
