Remove airoha_gdm_port dependency in ETS tc callback signatures and rely on net_device pointer instead. Please note this patch does not introduce any logical change and it is a preliminary patch in order to support multiple net_devices connected to the same GDM3 or GDM4 port via an external hw arbiter.
