orangepi-5-plus ethernet question

In your latest release, the wired network card of Orange Pi 5 Plus has a high latency. When pinging, the latency varies from 1 to 3 ms. In the kernel images of Armbian 6.1.75 and above, the latency is within 0.5 ms. I'm not sure if it's a kernel issue. Please merge the latest linux - rockchip kernel. Thank you.
