My project is just provided by Altera.

My SOPC is WEB_SERVER(rgmii) provided by CD of DE2-115.

MY software is simple_socket_server(RGMII)

I need to change something in SOPCBuilder or top level file? The datasheet of 88E1111 show me that the frequency, provided for PHY, is changed automatically.

When it is 1000Mbps, we get 125Mhz.

When it is 100Mbps, we get 25Mhz.
