If the environment variable "ethact" is not set, the first device in the uclass is returned. This depends on the probing order of the ethernet devices. Moreover it is not not configurable at all.
Try to return the ethernet device with sequence id 0 first which then can be configured by the aliases in a device tree. Fall back to the old mechanism in case of an error.
