Asunto: r8169: issues with RTL8125BG on Raspberry Pi 5 + OpenWrt

Hello all,

I'm having some issues with r8169 on a Raspberry Pi 5 running OpenWrt
(kernel v6.6.34) + RTL8125BG (MCUZone MP2.5G).

As you can see in the following logs, it crashes with " transmit queue 0
timed out".
It works perfectly fine for about less than 1 minute and then it crashes.
The crash appearance can be sped up by running a speed test or anything that
increases the network load.

Maybe it's a HW issue since the official r8125 driver crashes too...

Thanks for the report and this relevant information. If the vendor driver fails
too, this indeed makes is likely that the root cause is not with the r8169 driver.
According to your logs the NIC's even come w/o a pre-programmed MAC address.

In the following links you can find the logs from the different tests that I
carried out with both r8169 and r8125 drivers.

1. OpenWrt + kernel v6.6.34 + r8169 + ASPM Disabled

2. OpenWrt + kernel v6.6.34 + r8169 + ASPM Enabled

3. OpenWrt + kernel v6.6.34 + r8125 v9.012.04

4. OpenWrt + kernel v6.6.34 + r8125 v9.013.02

BTW, the same device (RPi 5) is running perfectly fine with a USB3 ethernet
adapter (RTL8165B + r8152 driver).

I've ordered another board based on the RTL8111H so I can check if that
works with r8169 or not.
