The driver of sgmii is tested successfully under uboot, and the file can be downloaded,Only the device tree is configured in the kernel. I don't know if this configuration is feasible. Please give me a suggestion.

Thank you

Please refer to LX2160ARDB board Specifications from https://www.nxp.com/design/qoriq-developer-resources/layerscape-lx2160a-reference-design-board:LX216...

there is no SGMII PHY on the target board, so it is impossible to configure the Ethernet port of LX2160ARDB as SGMII mode.
