From: Nazim Amirul <redacted> Russell King's commit de696c63c1dc ("net: stmmac: socfpga: convert to use phy_interface") replaced mac_interface with phy_interface in socfpga_get_plat_phymode(), noting that no upstream DTS files set the "mac-mode" property, making the two values identical. The Agilex5 SoCDK TSN Config2 board is an exception: its gmac1 TSN port uses GMII internally in the MAC while the PHY-side interface is RGMII, so mac-mode and phy-mode differ.Maybe you need to represent the hardware block which magically converts GMII to RGMII in DT?
Yeah that's what we have on CycloneV, and we force the INTF_SEL to GMII if that HW block is present. I wonder if there's the same on agileX5 ?
