I have just used OpenSUSE Tumbleweed with the very recent Kernel 5.14.6-1-default, which works mostly perfect. I am happy to confirm that the 1G RJ45-Port now works out of the box with this kernel. In fact, there are no more warnings up until `fsl_mc_dpio` is loaded: ```auto [14.732750] fsl_mc_dpio dpio.14: probed [14.737781] fsl_mc_dpio dpio.13: Adding to iommu group 0 [14.745525] fsl_mc_dpio dpio.13: unknown SoC version [14.775314] fsl_mc_dpio dpio.13: probed [...] [15.138743] fsl_mc_dpio dpio.1: Adding to iommu group 0 [15.146263] fsl_mc_dpio dpio.1: unknown SoC version [15.170320] fsl_mc_dpio dpio.1: probed [15.173450] fsl_mc_dpio dpio.0: Adding to iommu group 0 [15.181233] fsl_mc_dpio dpio.0: unknown SoC version [15.187358] fsl_mc_dpio dpio.0: probed ``` To use the SFP±Ports it is recommended in the [Documentation for OpenSUSE Leap 15.3](https://github.com/SolidRun/Documentation/blob/bsp/lx2k/suse-leap-152.md), so I have built NXP’s `restool` on Openbuild: [https://software.opensuse.org//download.html?project=home%3Awind.gmbh&package=restool](https://software.opensuse.org//download.html?project=home%3Awind.gmbh&package=restool) When I try to bring `dpmac.9` up I get the following message: ```auto # ls-addni dpmac.9 error: Did not find a device file Restool wrapper scripts only support the latest major MC version that currently is MC10.x.

The kernel needs to be built with CONFIG\_FSL\_MC\_UAPI\_SUPPORT=y for restool to work. If this is a distro kernel and the config option is not enabled, then please file a bug with your distribution to enable the feature. ---
