Hi Dimistry,

Do you only using the Start of Frame control byte only?

XGMII is required to have the Start Of Frame control byte aligned to lane/byte 0 and the SFD aligned to lane 3 with the first byte of the packet on lane 0 but GMII (being a byte interface) is only required to align the Start of Frame control byte to lane 0.

Best regards,
