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