Hi Krzysztof, [...] > This patch makes the RTL8111 work on i.MX6. Would it be possible to implement this particular MRRS fix as a quirk only for the i.MX6 controller? Unless this is something that we need in the core, a quirk would be preferred over something that changes the PCI core. An example of such quirk might be the one currently implemented for the Loongson controller, as per: https://elixir.bootlin.com/linux/v5.14-rc5/source/drivers/pci/controller/pci-loongson.c#L63 Krzysztof
