Using Imx6

I am trying to run ethernet on my custom board

so i am following the below link for my reference

U-Boot Migration Example 

following parameter is

#define CONFIG_FEC_MXC_PHYADDR  0x18

as per output of mii info

following is the console

As per the document i need to have vitesse driver and change in include/configs/mx6var_som.h file as i am using vitesse vsc8502 phy

i found vitesse.c but its not having driver for vsc8502

How to get the driver or uboot will find its own generic phy

and why the error is coming phy not found
