Changed disassociate reason to 0x07 when spoofing a disassociate
frame. This along with 0x06 are the only two reason codes that
should be accepted in an unprotected disassociate frame.
Using the hwsim dbus interface ".Interface" under the radios
object you can now send an arbitrary frame out from that radio.
Two methods have been added, spoof_frame and spoof_disassociate.
In the beacon loss test try to simulate a periodic communication problem
because we don't support roaming if the AP goes away completely.
2 seconds seems to be enough to consistently trigger the beacon_loss
event without triggering a disconnect by the linux kernel or hiding the AP
from the roam scan. Also set the RSSI for that AP lower so that it is
not reselected by iwd.
