I'm still not sure this belongs in devlink.
What about devices that support roce and iwarp concurrently?
There is nothing at the protocol level that precludes this - doesn't
this device allow it?
I know Parav is looking at the general problem of how to customize
what aux devices are created, that may be a better fit for this.
Can you remove the devlink parts to make progress?
