I do not need the auto-detection of the phy-mode nor any RX/TX delay (these are fixed values) however, from that patch-set I would need most of phy_rgmii_probe_interface() (and all of the helpers it's using) also I'm wondering if the "protocol" 0x0808 is recommended over ETH_P_EDSA Best regards, Martin
