    Pengpeng,

    Welcome to e2e.

    The RGMII and MII are relatively slow signals with max 125MHz/250Mbps max data rate. Following general good design and layout guidelines with trace length matching for TX/RX, avoiding stubs, sharp corners, impedance matching would be sufficient for these signals.
