It is true, but as can be seen from:
Documentation/devicetree/bindings/net/dsa/realtek-smi.txt
it is a family of 8 switches. I think we should just have
one module handling all of them for simplicity, once we
get around to implementing anything else than RTL8366RB
that is.

It's these 8 switches that talk SMI and they have a lot
in common like talking RRCP internally AFAICT.
I think these switches are pretty complex on the inside,
we just don't have very good documentation :/
