* The bus layer registers to the bus driver, advertises the supported HW and
* gets notifications about enumeration, suspend, resume.
* For the moment, the bus layer is not a linux kernel module as itself, and
* the module_init function of the driver must call the bus specific

*
* The iwl_bus describes the data that is shared amongst all the bus layer

* specific area is not visible outside the bus specific implementation.
* iwl_bus holds a pointer to iwl_shared which holds pointer to all the other
* layers of the driver (iwl_priv, iwl_trans). In fact, this is the way to go
* when the transport layer needs to call a function of another layer.

* layer must be here.
* The shared area also holds pointer to all the other layers. This allows a

* gets notifications about enumeration, suspend, resume.
* For the moment, the bus layer is not a linux kernel module as itself, and
* the module_init function of the driver must call the bus specific
* registration functions. These functions are listed at the end of this file.
* For the moment, there is only one implementation of this interface: PCI-e.
