On Samsung exynos5440 sleds board, ethernet phy is attached as the fixed phy mode, which can be
seen from the following part in arch/arm/boot/dts/exynos5440-sd5v1.dts of linux kernel:

    gmac: ethernet@00230000 {
        fixed-link {
            speed = <1000>;
            full-duplex;
        };
    };

Unfortunately the above dts definition doesn't use the standard fixed link dts binding, also the ethernet
driver of stmmac doesn't parse fixed link binding, so cause ethernet not workable at all on utopic.

The two patches in below tree can add the fixed link support in stmmac and changes the fixed link
description into current standard binding:

git://kernel.ubuntu.com/ming/ubuntu-utopic.git exynos5440-net-fix

72bf502 UBUNTU: SAUCE: (no-up) net: stmmac: add fixed_phy support via
fixed-link DT binding
65a6d09 UBUNTU: SAUCE: (no-up) ARM: exynos5440-sd5v1: switch to
fixed-link DT binding

Thanks,
