-/*----------------------------------------------------------------
-* 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:
-* process thread
