Great.

The MDIO bus is now logically not connected to eth0. Instead you have
the fixed-link mdio device connected to eth0. So SIOCSMIIREG calls on
eth0 now try to manipulate the fixed link phys.
However, i think you can still access the MDIO bus, just use eth1 in
your ioctl call.
You should however consider writing a DSA driver for the switch.
