If it's a recent lime2, you need to update your u-boot to the latest package
version. I commited a fix for this yesterday.
Make sure you update sysutils/u-boot/, this is were the change really is.

(long version: the newer lime2 boards use a different phy - a micrel one -
 and it needs a different timing setup. CONFIG_GMAC_TX_DELAY=4 in the
 u-boot config file fixes it. This is what
 sysutils/u-boot/patch-configs_A20-OLinuXino-Lime2*_defconfig do).
