Hi Tony, there are two ethernet interfaces ( dual-emac-configuration ) used. One is connected to another 100mbit switch-ic ( refclk should come from switch ic ) via rmii, the other one is connected to a 1gbit fpga rgmii interface ( where the clock is served from the fpga ). On both interfaces it may happen that the clock isn't present while the mac-address is set (fpga may not have been inited, switch chip could be held in reset), but this was the same behaviour with previous kernel (3.14 with cpsw patched from ti tree) where this configuration worked. As the hardware is in field now there is no chance to change hardware. On the other hand: when not setting the mac of the interface that early, the cpsw seems to init proberly but a ping to the outer world does not work either, so something else may be different on the new kernel.
