* DOC: Life cycle of the transport layer
*
* The transport layer has a very precise life cycle.
*
* 1) A helper function is called during the module initialization and
* registers the bus driver's ops with the transport's alloc function.
* 2) Bus's probe calls to the transport layer's allocation functions.
* Of course this function is bus specific.
* 3) This allocation functions will spawn the upper layer which will
* register mac80211.
*
* 4) At some point (i.e. mac80211's start call), the op_mode will call
* the following sequence:
* start_hw
* start_fw
*
* 5) Then when finished (or reset):
* stop_fw (a.k.a. stop device for the moment)
* stop_hw
*
* 6) Eventually, the free function will be called.
