phylink already supports 2500 and 10G fixed-link (actually, it doesn't care too much about the speed value, just passing it through), provided phy_lookup_setting() and the MAC support the speed. Since it doesn't bother with emulating a set of phy registers, which then would be read by phylib and translated back to a speed and duplex for the MAC to use, it's way more flexible when it comes to the old emulated-phy fixed links code. What it doesn't do is provide an emulation of C45 PHYs for mii-tool/ mii-diag - ethtool is the way forward, and it supports ethtool for these speeds. -- 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
