That > would make thinks simple. There is no difference in the ID registers of the RTL8218 that is attached to RTL83xx/RTL93xx or to possible other SOCs. The RTL8218 series has a lot in common with the lower port designs (e.g. RTL8211). They are driven by dual QSGMII and can be attached to any non Realtek SOC. If upstream rtlgen_read_mmd() is not the proper way then I must think about it. But that needs to wait a bit ... Markus
