/*
* Some boards do not have a PHY for each ethernet port . These ports
* are known as Fixed PHY ( or PHY - less ) ports . For such ports , set
* the appropriate CONFIG_PHY_ADDR equal to CONFIG_FIXED_PHY and
* then define CONFIG_SYS_FIXED_PHY_PORTS to define what the speed and
* duplex should be for these ports in the board configuration
* file .
*
* For Example :
* # define CONFIG_FIXED_PHY 0xFFFFFFFF
*
* # define CONFIG_PHY_ADDR CONFIG_FIXED_PHY
* # define CONFIG_PHY1_ADDR 1
* # define CONFIG_PHY2_ADDR CONFIG_FIXED_PHY
* # define CONFIG_PHY3_ADDR 3
*
* # define CONFIG_SYS_FIXED_PHY_PORT ( devnum , speed , duplex ) \
* { devnum , speed , duplex } ,
*
* # define CONFIG_SYS_FIXED_PHY_PORTS \
* CONFIG_SYS_FIXED_PHY_PORT ( 0 , SPEED_100 , DUPLEX_FULL ) \
* CONFIG_SYS_FIXED_PHY_PORT ( 2 , SPEED_100 , DUPLEX_HALF )
