Maybe the internal IP supports this but the SoC doesn't? However, I was asking about interfaces rather than speeds - so RGMII, SGMII, 2500BASE-X... is there a mention of anything else? -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up. Decent connectivity at last!
