Since then, I have worked on refactoring the implementation as follow: My apology in sending v2 patch series that miss 1/7 patch, please ignore. v3 changes: 1/7 - [New] Update xpcs_do_config to accept advertising input 2/7 - [New] Fix to compilation issue introduced v1. Update xpcs_do_config for sja1105. 3/7 - Same as 3/4 of v1 series. 4/7 - [Fix] Fix numerous issues identified by Russell King [1]. 5/7 - [New] Make fixed-link setting takes precedence over ovr_an_inband. This is a fix to a bug introduced earlier. Separate patch will be sent later. 6/7 - [New] Allow phy-mode ACPI _DSD setting for dwmac-intel to overwrite the phy_interface detected through PCI DevID. 7/7 - [New] Make mdio register flow to skip PHY scanning if fixed-link is specified. I have tested the patch-series on a 3-port SGMII Ethernet on Elkhart Lake customer platform and PSE GbE1 (0000:00:1d.2) is setup for fixed-link with below ACPI _DSD modification based on [3]:- Device (OTN1) { Name (_DSD, Package () { ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"), Package () { Package () {"phy-mode", "1000base-x"}, }, ToUUID("dbb8e3e6-5886-4ba6-8795-1319f52a966b"), Package () { Package () {"fixed-link", "LNK0"} } }) Name (LNK0, Package(){ // Data-only subnode of port ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"), Package () { Package () {"speed", 1000}, Package () {"full-duplex", 1} } }) } The modified ACPI DSDT table is inserted into OS based on [4] for testing purpose. This method will not be required if respective BIOS has the matching ACPI _DSD changes. In gist, we avoid the need to add board specific DMI based configuration to Linux driver and let ACPI DSDT table customized according to hardware/port configuration design to decide how the driver is loaded up per port-basis. From dmesg below (whereby non-relevant section removed), we can see that:- [ 4.112037] intel-eth-pci 0000:00:1d.1 eno1: configuring for inband/sgmii link mode [ 4.132016] intel-eth-pci 0000:00:1d.2
