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 ? Or is it in half duplex mode ?

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 at 1000MB/s ? Or is it in half duplex mode ?
