Andre, the 3.14 kernel you are talking, is it this one ? :? https://github.com/hardkernel/linux/tree/odroidc2-3.14.y Because in drivers/net/phy/realtek.c, they disable EEE, but also?1000Base-T Full Duplex advertisement ? + /* disable 1000m adv*/ + val = phy_read(phydev, 0x9); + phy_write(phydev, 0x9, val&(~(1<<9))); If this is the kernel you are running, you should not be able to have ethernet@1000MB/s ?
