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