| * 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 |
