We met possibly the same problem when testing nvidia/mellanox's
GPUDirect RDMA product, we found that changing NET_SCH_DEFAULT to
DEFAULT_FQ_CODEL mitigated the problem, having no idea why. Maybe you
can also have a try?
Besides, our testing is pretty complex, do you have a quick test to
reproduce it?
