As a result multiple net_devices can connect to the same GDM{3,4} port and there is a theoretical "1:n" relation between GDM ports and net_devices. Introduce the ethernet-port property in order to model a given net_device that is connected via the external arbiter to the GDM{3,4} port (that is represented by the ethernet property. Please note GDM1 or GDM2 does not support the connection with the external arbiter and are represented by ethernet property.
