I also don't know but the most important issue is that "stm32_eth_init"
have to be called. But to achive it you have to have properly configured system.
Please look below.

Sorry for such basic question but do you have such packages like:
CYGPKG_IO_ETH_DRIVERS, network driver and so on?
BTW.
Maybe in this way it will be easier. Generally if I like to add
new eth/phy driver I create eCos configuration file with using template
usually "lwIP for Ethernet" and proper hardware target. After that
I didn't have any problem with "calling" eth/phy driver.
Could you provide information about your target?
Is it any known reference board?
Do you have HAL (BSP) for it?
