This patch series is based on next-20230525. This patch series can improve performance of TX in a specific condition. The previous code used "global rate limiter" feature so that this is possible to cause performance down if we use multiple ports at the same time. To resolve this issue, use "per-queue rate limiter" feature instead. To use the feature, we need to refactor the rswitch driver, especially got the internal bus clock rate and calculate the value for the feature.
