RTL8169 inherited a lot from RTL8139, so I would expect that the r8169 driver could be a good basis for a RTL8125 mainline driver. > [1] https://www.realtek.com/en/press-room/news-releases/item/realtek-launches-world-s-first-single-chip-2-5g-ethernet-controller-for-multiple-applications-including-gaming-solution > [2] https://www.realtek.com/en/component/zoo/category/network-interface-controllers-10-100-1000m-gigabit-ethernet-pci-express-software > [3] https://github.com/endlessm/linux/commit/da1e43f58850d272eb72f571524ed71fd237d32b > > Jian-Hong Pan > Heiner ^ permalink raw reply [flat|nested] 6+ messages in thread

Most parts are quite similar to RTL8168. However the PHY handling is quite weird. 2.5Gbps isn't covered by Clause 22, but instead of switching to Clause 45 Realtek uses Clause 22 plus a proprietary chip register (for controlling the 2.5Gbps mode) that doesn't seem to be accessible via MDIO bus. This may make using phylib tricky. >> [1] https://www.realtek.com/en/press-room/news-releases/item/realtek-launches-world-s-first-single-chip-2-5g-ethernet-controller-for-multiple-applications-including-gaming-solution >> [2] https://www.realtek.com/en/component/zoo/category/network-interface-controllers-10-100-1000m-gigabit-ethernet-pci-express-software >> [3] https://github.com/endlessm/linux/commit/da1e43f58850d272eb72f571524ed71fd237d32b >> >> Jian-Hong Pan >> > Heiner > Heiner ^ permalink raw reply [flat|nested] 6+ messages in thread
