This makes it difficult to validate regression stability when modifying the provider/consumer APIs or aggregation logic. Introduce a kunit test suite that verifies the fundamental behavior of the subsystem. The tests cover: - Provider API (node creation, linking, topology construction). - Consumer API (path enabling/disabling, bandwidth requests). - Standard aggregation logic (accumulating bandwidth across links). - Bulk operations for setting bandwidth on multiple paths. The suite simulates a simple SoC topology with multiple masters and a shared bus to validate traffic aggregation behavior in a controlled software environment, without requiring specific hardware or Device Tree support.
