Certain serial SERDES protocols like 1000base-x, 2500base-x, SGMII, USXGMII can operate either in a mode where the PHY (be it on-board or inside an SFP module) passes the link parameters (speed, duplex, pause) to the MAC through in-band through control words standardized by IEEE 802.3 clause 37, or
