No need to have a special config variable for the PA type, we can just use the additional NIC config function to config the hardware correctly.

/**
|
|
* 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
