Interfacing Cyclone IV FPGA with Marvell PHY 88E1111 using SGMII

Hi I am using the cyclone IV with SGMII interfaced with Marvell PHY 88E1111. So what are the registers to be configured in the phy and how can I configure it for SGMII.

If you have a look at the Altera driver, there is a marvell_cfg_sgmii that does that in the file altera\**.*\ip\altera\triple_speed_ethernet\lib\sopc_builder\altera_triple_speed_ethernet\HAL\src\altera_avalon_tse.c

I have no idea how you are supposed to use this function if you are using the driver though. Are you using a development kit? Aren't there any example designs with Ethernet?
