   43 /*
   44  * The Aironet 4500/4800 series cards come in PCMCIA, ISA and PCI form.
   45  * This driver supports all three device types (PCI devices are supported
   46  * through an extra PCI shim: /sys/dev/an/if_an_pci.c). ISA devices can be
   47  * supported either using hard-coded IO port/IRQ settings or via Plug
   48  * and Play. The 4500 series devices support 1Mbps and 2Mbps data rates.
   49  * The 4800 devices support 1, 2, 5.5 and 11Mbps rates.
   50  *
   51  * Like the WaveLAN/IEEE cards, the Aironet NICs are all essentially
   52  * PCMCIA devices. The ISA and PCI cards are a combination of a PCMCIA
   53  * device and a PCMCIA to ISA or PCMCIA to PCI adapter card. There are
   54  * a couple of important differences though:
   55  *
   56  * - Lucent ISA card looks to the host like a PCMCIA controller with
   57  *   a PCMCIA WaveLAN card inserted. This means that even desktop
   58  *   machines need to be configured with PCMCIA support in order to
   59  *   use WaveLAN/IEEE ISA cards. The Aironet cards on the other hand
   60  *   actually look like normal ISA and PCI devices to the host, so
   61  *   no PCMCIA controller support is needed
   62  *
   63  * The latter point results in a small gotcha. The Aironet PCMCIA
   64  * cards can be configured for one of two operating modes depending
   65  * on how the Vpp1 and Vpp2 programming voltages are set when the
   66  * card is activated. In order to put the card in proper PCMCIA
   67  * operation (where the CIS table is visible and the interface is
   68  * programmed for PCMCIA operation), both Vpp1 and Vpp2 have to be
   69  * set to 5 volts. FreeBSD by default doesn't set the Vpp voltages,
   70  * which leaves the card in ISA/PCI mode, which prevents it from
   71  * being activated as an PCMCIA device.
   72  *
   73  * Note that some PCMCIA controller software packages for Windows NT
   74  * fail to set the voltages as well.
   75  *
   76  * The Aironet devices can operate in both station mode and access point
   77  * mode. Typically, when programmed for station mode, the card can be set
   78  * to automatically perform encapsulation/decapsulation of Ethernet II
   79  * and 802.3 frames within 802.11 frames so that the host doesn't have
   80  * to do it itself. This driver doesn't program the card that way: the
   81  * driver handles all of the encapsulation/decapsulation itself.
