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.
QSGMII：Quad serial Gigabit Medium Independent Interface 4路
PSGMII: Penta-Serial Gigabit Media Independent Interface 5路
相关网口概念：
serdes:serialize/deserializer 串行器/解串器
