The default behavior in the latest u-boot revisions is to rotate the active net device to the next available if the requested link is not established.
For our ls102x based devices this would mean that if active debug net device is not available, u-boot will rotate and set the next net device that is one of the estar adapters. To return from this situation manual action to set correct ethact adapter will be needed and this can be annoying when working in debug mode.
Setting ethrotate=no will disable net adapter rotation and will make sure that the primary adapter is always used.
