Simulating devices
==================
The Linux driver mac80211_hwsim provides the functionality to simulate
Wireless devices using fake virtual air. Just load the module.
modprobe mac80211_hwsim radios=0
Provding the radios=0 is important since otherwise it starts out with
two new Wireless radios by default.
With the provided hwsim utility it is now possible to add and remove
virtual radio devices.
hwsim --create
hwsim --destroy=<radio-id>
The radio id assigned to each virtual device is its internal id used
by the Wireless device.
