MII: Medium Independent Interface 媒体独立接口，也称介质无关接口

RMII: Reduced MII 简化媒体独立接口

GMII: Gigabit Medium Independent Interface 千兆媒体独立接口

RGMII: Reduced GMII

SGMII: Serial Gigabit Media Independent Interface 串行千兆位媒质独立接口

SGMII is serial GMII interface which uses only 4 lines to connect with MAC/SOC. When copper-side
link is established, SGMII will pass the copper-side link status (link, speed, duplex) to MAC side for
building the link. SGMII interface shares the same SerDes with fiber port.
