The problem is... the stmmac driver is utter bollocks - that information is *not* passed to the BSP. Instead, stmmac parse and store information such as the PHY interface mode at initialisation time. BSPs also re- parse and store e.g. the PHY interface mode at initialisation time. The driver ignores what it gets from phylink. The driver is basically utter crap. That's an area I _had_ patches to clean up. I no longer do. stmmac is crap crap crap and will stay crap until they become more receptive to patches to fix it, even if the patches are not 100% to their liking but are in fact correct. Maybe if I ever decide to touch that driver in the future. Which I doubt given my recent experience. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up. Decent connectivity at last!
