Well, depends. Our driver just asks the firmware to do the scan, and it

I do not want to offload scanning in user-space, which is the equivalent
of what your driver is doing as far as the kernel is concerned? If someone wants
to do that in the future, then sure, they can implement such a thing.
Well, the question isn't really that offloading, the question is what
happens with the hw-scan logic in hwsim? Though I guess now that I think
about it, that wouldn't show up in userspace at all with your changes.
I think for HW scan and related matters, you treat user-space like a firmware
target, so you send it a message, and then get some response or action, similar
to how you would request ath10k or some USB dongle NIC to do things for you.
My own interest in hwsim user-space is to make it act more like ath9k
than a firmware target driver, but I don't think my changes preclude doing
target based emulation in the future.
Thanks,
Ben
