When you are using your own hardware, you may have to adapt the FEC
driver.
The driver is currently written for the Viper board. Look in function
fec_eth_init (file if_fec.c) for the section "// Reset PHY" and change
the IOs appropriate to your hardware design (as a quick workaround).

ESA is the Ethernet- (or MAC-) address (i think so). If the init
function does not find a Flash configuration (= ESA unknown) it uses a
default address. I have to fix this myself, but for now this
configuration is working for me.
