Therefore, the WBM idle ring buffers choose the implicit return buffer manager (DEV0_IDLE_DESC_LIST). However, this implicit return buffer manager design not meeting the requirements to support inter device MLO. In inter device MLO, multiple devices participate. The device specific WBM idle ring buffers transmit to multiple device REO rings. To distinguish between device specific WBM idle buffers, the setup configuration need to choose a different return buffer manager based on the unique identifier (device index).
