Aironet PCI shim; all the real meat is in sys/ic/an.c.

Based on the FreeBSD if_an_pci.c but really the only things that
remain the same are the informative comments at the top.  I retained
Bill Paul's Copyright since it seems silly to add my own copyright
to what is simply boilerplate.

+/*
+ * 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.
