Hi Russell

I tested both of these with my board. It is a Freescale Vybrid, using
the FEC ethernet driver, and i have three switches attached, using
mdio-mux to give three mdio busses.

No obvious regressions, my board boots, the switches are all present
and correct. I built the FEC driver as a module, and it won't unload:

 kernel:unregister_netdevice: waiting for eth1 to become free. Usage count = 1
unregister_netdevice: waiting for eth1 to become free. Usage count = 1

i assume because DSA holds a reference. I've not tried a fully module
build, DSA has issues with that.
