Andre, I checked again the kernel at https://github.com/hardkernel/linux/tree/ odroidc2-3.14.y. The version you mention (3.14.65-73) seems to be: sha1: c75d5f4d1516cdd86d90a9d1c565bb0ed9251036 tag: jenkins-deb s905 kernel-73 In this particular version, both realtek drivers: - drivers/net/phy/realtek.c - drivers/amlogic/ethernet/phy/am_realtek.c have the hack to disable 1000M advertisement. I don't understand how it possible for you to have 1000Base-T Full Duplex with this, maybe I'm missing something here ? If you did compile the kernel yourself, could you check the 2 file mentioned above ? Just to be sure there was no patch applied at the last minute, which would not show up in the git history of hardkernel ? Thx Jerome > >
