[PATCH net-next v4 05/11] net: dsa: realtek: use phy_read in ds->ops

Luiz Angelo Daros de Luca
2022-01-05T03:16:02Z

The ds->ops->phy_read will only be used if the ds->slave_mii_bus
was not initialized. Calling realtek_smi_setup_mdio will create a
ds->slave_mii_bus, making ds->ops->phy_read dormant.

Using ds->ops->phy_read will allow switches connected through non-SMI
interfaces (like mdio) to let ds allocate slave_mii_bus and reuse the
same code.
