====================
net: airoha: Preliminary patches to support multiple net_devices connected to the same GDM port
EN7581 or AN7583 SoCs support connecting multiple external SerDes (e.g.
Ethernet or USB SerDes) to GDM3 or GDM4 ports via a hw arbiter that
manages the traffic in a TDM manner. 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.

This is a preliminary series to introduce support for multiple net_devices
connected to the same Frame Engine (FE) GDM port (GDM3 or GDM4) via an
external hw arbiter.
