dsa: Split ops up, and avoid assigning tag_protocol and receive separately
This change addresses several issues.
First, it was possible to set tag_protocol without setting the ops pointer.
To correct that I have reordered things so that rcv is now populated before
we set tag_protocol.
Second, it didn't make much sense to keep setting the device ops each time a
new slave was registered. So by moving the receive portion out into root
switch initialization that issue should be addressed.
Third, I wanted to avoid sending tags if the rcv pointer was not registered
so I changed the tag check to verify if the rcv function pointer is set on
the root tree. If it is then we start sending DSA tagged frames.
Finally I split the device ops pointer in the structures into two spots. I
placed the rcv function pointer in the root switch since this makes it
easiest to access from there, and I placed the xmit function pointer in the
slave for the same reason.
