Subject: [PATCH net-next 7/7] net: dsa: realtek: always use the realtek user mdio driver
Although the DSA switch will register a generic mdio driver when
ds_ops.phy_{read,write} exists ("dsa user smi"), it was pointed out that
it was not a core feature to depend on [1]. That way, the realtek user
mdio driver will be used by both interfaces.
[1] https://lkml.kernel.org/netdev/20220630200423.tieprdu5fpabflj7@bang-olufsen.dk/T/
The ds_ops field in realtek_priv was also dropped as now we can directly
reference the variant->ds_ops.
