* prism2sta_probe_pci
*
* Probe routine called when a PCI device w/ matching ID is found.
* The ISL3874 implementation uses the following map:
* BAR0: Prism2.x registers memory mapped, size=4k
* Here's the sequence:
* - Allocate the PCI resources.
* - Read the PCMCIA attribute memory to make sure we have a WLAN card
* - Reset the MAC
* - Initialize the netdev and wlan data
* - Initialize the MAC
*
* Arguments:
* pdev ptr to pci device structure containing info about
* pci configuration.
* id ptr to the device id entry that matched this device.
*
* Returns:
* zero - success
* negative - failed
*
* Side effects:

* Call context:
