Quentin Schulz eb7fd7aa35 net: stmmac: platform: guarantee uniqueness of bus_id ... bus_id is currently derived from the ethernetX alias. If one is missing for the device, 0 is used. If ethernet0 points to another stmmac device or if there are 2+ stmmac devices without an ethernet alias, then bus_id will be 0 for all of those. This is an issue because the bus_id is used to generate the mdio bus id (new_bus->id in drivers/net/ethernet/stmicro/stmmac/stmmac_mdio.c stmmac_mdio_register) and this needs to be unique. This allows to avoid needing to define ethernet aliases for devices with multiple stmmac controllers (such as the Rockchip RK3588) for multiple stmmac devices to probe properly. Obviously, the bus_id isn't guaranteed to be stable across reboots if no alias is set for the device but that is easily fixed by simply adding an alias if this is desired.
