* prism2sta_config

|
* a card insertion event. At this point, we _know_ there's some
|
|
* physical device present. That means we can start poking around
|
|
* at the CIS and at any device specific config data we want.
|
|
*
|
|
* Note the gotos and the macros. I recoded this once without
|
|
* them, and it got incredibly ugly. It's actually simpler with
|
|
* them.
|
|
*
|
|
* Arguments:
|
|
* link the dev_link_t structure created in attach that
|
|
* represents this device instance.
|
|
*
|
|
* Returns:
|
|
* nothing
|
|
*
|
|
* Side effects:
|
|
* Resources (irq, io, mem) are allocated
|
|
* The pcmcia dev_link->node->name is set
|
|
* (For netcards) The device structure is finished and,
|
|
* most importantly, registered. This means that there
|
|

|

* userland.

* beware". Your system might supply 5v to a 3v card

|
