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.
