/*
* This is a PCI shim for the Aironet PC4500/4800 wireless network
* driver. Aironet makes PCMCIA, ISA and PCI versions of these devices,
* which all have basically the same interface. The ISA and PCI cards
* are actually bridge adapters with PCMCIA cards inserted into them,
* however they appear as normal PCI or ISA devices to the host.
*
* All we do here is handle the PCI match and attach and set up an
* interrupt handler entry point. The PCI version of the card uses
* a PLX 9050 PCI to "dumb bus" bridge chip, which provides us with
* multiple PCI address space mappings. The primary mapping at PCI
* register 0x14 is for the PLX chip itself, *NOT* the Aironet card.
* The I/O address of the Aironet is actually at register 0x18, which
* is the local bus mapping register for bus space 0. There are also
* registers for additional register spaces at registers 0x1C and
* 0x20, but these are unused in the Aironet devices. To find out
* more, you need a datasheet for the 9050 from PLX, but you have
* to go through their sales office to get it. Bleh.
