tobyxdd：暂无非标准内核支持计划，请尝试实验分支
作者原文@tobyxddI don't really plan to support non-standard kernels, and your fix is not correct either. That said, this change is caused by the BBRv3 patch, which may eventually make its way into the mainline kernel, so it's worth looking into.
could you try this branch and see if it works for you?
