The closed nature of the USXGMII spec makes it very hard for us to know whether your implementation is correct or not. I have some documentation which suggests that USVGMII is a USXGMII link running at "5GR" rate as opposed to USXGMII running at "10GR" rate. So, I think 5G mode should be left out until it becomes clear that (a) we should specify it as USXGMII with a 5G rate, or as USVGMII. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line in suburbia: sync at 12.1Mbps down 622kbps up According to speedtest.net: 11.9Mbps down 500kbps up
