37 * This is a PCI shim for the Aironet PC4500/4800 wireless network
38 * driver. Aironet makes PCMCIA, ISA and PCI versions of these devices,
39 * which all have basically the same interface. The ISA and PCI cards
40 * are actually bridge adapters with PCMCIA cards inserted into them,
41 * however they appear as normal PCI or ISA devices to the host.
42 *
43 * All we do here is handle the PCI probe and attach and set up an
44 * interrupt handler entry point. The PCI version of the card uses
45 * a PLX 9050 PCI to "dumb bus" bridge chip, which provides us with
46 * multiple PCI address space mappings. The primary mapping at PCI
47 * register 0x14 is for the PLX chip itself, *NOT* the Aironet card.
48 * The I/O address of the Aironet is actually at register 0x18, which
49 * is the local bus mapping register for bus space 0. There are also
50 * registers for additional register spaces at registers 0x1C and
51 * 0x20, but these are unused in the Aironet devices. To find out
52 * more, you need a datasheet for the 9050 from PLX, but you have
53 * to go through their sales office to get it. Bleh.
