Driver dependencies such as the fsl-mc bus or the dpio driver are out of 
staging but not all the TODO items are yet implemented (most notably support 
for control traffic).
Do you think maybe we can move it now and submit directly to the netdev tree 
the other features?

Thank you. BTW do you have any plans for moving this driver out of
staging? It looks pretty good to me to get promoted in tree, provided
that you also have all the dependencies in place etc.

Just FYI, I sent a patch set containing a similar patch verifying if the netdev 
is backed by the ethsw:
https://lkml.org/lkml/2019/2/6/216

I sent the entire patch set against the staging tree.
