iwlmei allows to integrate with the CSME firmware. There are
flows that are prioprietary for this purpose:

* Get the information the AP, the CSME firmware is connected
  to. This is useful when we need to speed up the connection
  process in case the CSME firmware has an TCP connection
  that must be kept alive across the ownership transition.
* Forbid roaming, which will happen when the CSME firmware
  wants to tell the user space not disrupt the connection.
* Request ownership, upon driver boot when the CSME firmware
  owns the device.
