/**
 | 
						|
 * DOC: Driver system flows - drv component
 | 
						|
 *
 | 
						|
 * This component implements the system flows such as bus enumeration, bus
 | 
						|
 * removal. Bus dependent parts of system flows (such as iwl_pci_probe) are in
 | 
						|
 * bus specific files (transport files). This is the code that is common among
 | 
						|
 * different buses.
 | 
						|
 *
 | 
						|
 * This component is also in charge of managing the several implementations of
 | 
						|
 * the wifi flows: it will allow to have several fw API implementation. These
 | 
						|
 * different implementations will differ in the way they implement mac80211's
 | 
						|
 * handlers too.
 | 
						|
 | 
						|
 * The init flow wrt to the drv component looks like this:
 | 
						|
 * 1) The bus specific component is called from module_init
 | 
						|
 * 2) The bus specific component registers the bus driver
 | 
						|
 * 3) The bus driver calls the probe function
 | 
						|
 * 4) The bus specific component configures the bus
 | 
						|
 * 5) The bus specific component calls to the drv bus agnostic part
 | 
						|
 *    (iwl_drv_start)
 | 
						|
 * 6) iwl_drv_start fetches the fw ASYNC, iwl_req_fw_callback
 | 
						|
 * 7) iwl_req_fw_callback parses the fw file
 | 
						|
 * 8) iwl_req_fw_callback starts the wifi implementation to matches the fw
