/**
* DOC: shared area - role and goal
*
* The shared area contains all the data exported by the upper layer to the
* other layers. Since the bus and transport layer shouldn't dereference
* iwl_priv, all the data needed by the upper layer and the transport / bus
* layer must be here.
* The shared area also holds pointer to all the other layers. This allows a
* layer to call a function from another layer.
*
* NOTE: All the layers hold a pointer to the shared area which must be shrd.
* A few macros assume that (_m)->shrd points to the shared area no matter
* what _m is.
*
* 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.
* This implementation is iwl-pci.c
