Another use-case for this patch-set is going to be the habanalabs driver.
The GAUDI ASIC is a PCI H/W accelerator for deep-learning which also exposes 
network ports.We are going to use this auxiliary-bus feature to separate our 
monolithic driver into several parts that will reside in different subsystems 
and communicate between them through the bus.

Thanks,
Oded
