I suspect that's because the ethernet support in the originally upstreamed 
SoCFPGA code never worked on the SoCDK in the first place. I think the SoCDK
uses EMAC1, but the mainline code uses EMAC0 for whatever reason.

Edit include/configs/socfpga_cyclone5.h and change:
-#define CONFIG_EMAC_BASE                SOCFPGA_EMAC0_ADDRESS
+#define CONFIG_EMAC_BASE                SOCFPGA_EMAC1_ADDRESS

Does this work ?

I zap'd the "run bridge_enable_handoff" thing and replaced it with "bridge 
enable" command. Could that be the case ?

Please let me know if some of the above help first. The network part should and 
if it does, then I will add a patch. The FPGA part should as well

Also, I separated the patches into smaller groups, which I will resubmit one 
more time, but you can find a merge of all of them at [1], so you don't have
to apply them by hand. Please be advised, that those branches will be replaced 
with a never ones, that's why there's the timestamp at the end of the name (so 
check the repository if there is no new topic/arm/socfpga-yyyymmdd). Also, I 
will likely garbage collect the old ones at some point.
