This interface allows different protocol modules to use their own unique IOB buffer sources and allocation strategies without interfering with each other. Representative examples are the IP protocol and the CAN protocol. The IP protocol generally transmits packets of varying lengths and requires relatively high peak throughput. In this case, to ensure higher performance, IOB_BUFSIZE is often configured to be relatively large, such as greater than 500. The CAN protocol generally transmits short packets of fixed length. In this case, to improve memory utilization, IOB_BUFSIZE is often configured to be relatively small, such as 16 or 64. To optimize the memory utilization when the IP protocol and the CAN protocol share the same core, this interface was added. Signed-off-by: zhanghongyu <zhanghongyu@xiaomi.com>
