But could you please still submit this bug report to linux-netdev? Fedora don't have the resources to fix this bug and the Raspberry Pi guys won't fix any issues in the Fedora kernel. We need to fix this in the mainline kernel or least inform the lan78xx maintainer about the issue. I'm not able to reproduce this issue on my RPi 3B+. In order to report your issue to the relevant maintainers please submit a bug report to the following addresses: Nicolas Saenz Julienne <nsaenzjulienne@xxxxxxx> Woojung Huh <woojung.huh@xxxxxxxxxxxxx> Microchip Linux Driver Support <UNGLinuxDriver@xxxxxxxxxxxxx> netdev@xxxxxxxxxxxxxxx linux-usb@xxxxxxxxxxxxxxx It's important to mention lan78xx in subject line.
