Hi,
this raises a design question. If the system is suspending or, worse, hibernating, how do you make sure the offloader and the device are suspended in the correct order? And what happens if you need to go into reset_resume() when resuming?
I guess we'd need to establish a device link when the binding from the offload driver is done. Then the PM order will be assured.
