76 * DOC: shared area - role and goal
78 * The shared area contains all the data exported by the upper layer to the
79 * other layers. Since the bus and transport layer shouldn't dereference
80 * iwl_priv, all the data needed by the upper layer and the transport / bus
82 * The shared area also holds pointer to all the other layers. This allows a
83 * layer to call a function from another layer.
85 * NOTE: All the layers hold a pointer to the shared area which must be shrd.
86 * A few macros assume that (_m)->shrd points to the shared area no matter
89 * gets notifications about enumeration, suspend, resume.
90 * For the moment, the bus layer is not a linux kernel module as itself, and
91 * the module_init function of the driver must call the bus specific
92 * registration functions. These functions are listed at the end of this file.
93 * For the moment, there is only one implementation of this interface: PCI-e.
94 * This implementation is iwl-pci.c
