Hi Vivien

I still think this API should be based on ps.

With the way you have restructured probe, this now also works, there
is no longer a read without PS in order to get the device ID.

Also, think about the case of reading/writing registers via Ethernet
frames. Such functions would need ps, bus and sw_addr is not useful.
