| |
Currently, phy_interface for TSN controller instance is set based on its PCI Device ID. For SGMII PHY interface, phy_interface default to PHY_INTERFACE_MODE_SGMII. As C37 AN supports both SGMII and 1000BASE-X mode, we add support for 'phy-mode' ACPI _DSD for port-specific and customer platform specific customization.
Thanks to Andrew Lunn's guidance in https://patchwork.kernel.org/comment/24827101/
