As there is a mechanism in PHY drivers to switch the PHY interface between SGMII and 2500BaseX according to link speed. In this case, the in-band AN mode should be switching based on the PHY interface as well, if the PHY interface has been changed/updated by PHY driver. For e.g., disable in-band AN in 2500BaseX mode, or enable in-band AN back for SGMII mode (10/100/1000Mbps).
