* The implementation goals were as follow :
* o Obvious : you should not need a PhD to understand what's happening,
- * the benefit is easier maintainance.

* o Flexible : it should accommodate a wide variety of driver
* implementations and be as flexible as the old API.
* o Lean : it should be efficient memory wise to minimise the impact

* Functions prototype uses union iwreq_data
