Issue with LAN7801 USB-to-Ethernet Adapter on RSB3720 with KSZ9897 Using Kernel 5.15

I am currently working with the KSZ9897 Ethernet switch connected to an RSB3720 board. The Ethernet ports have been configured correctly, but I am encountering an issue with the LAN7801 USB-to-Ethernet adapter when attempting to initialize the PHY. Details: Board: RSB3720 Switch: KSZ9897 Adapter: LAN7801 (USB-to-Ethernet) Kernel Version: 5.15 Issue: The LAN7801 is unable to detect the PHY driver, as indicated by the kernel logs. Kernel Logs:

I have added debugging information to trace the issue, and it appears that the phydev pointer is not being initialized properly, resulting in the PHY driver not being detected. Request: Could you please provide guidance or any known solutions for this issue? Specifically, I am seeking advice on: Proper configuration for the LAN7801 PHY driver. Any additional kernel configurations or patches that might be required. Known compatibility or issues with KSZ9897 on kernel version 5.15.
