33 * Aironet 4500/4800 802.11 PCMCIA/ISA/PCI driver for FreeBSD.
35 * Written by Bill Paul <wpaul@ctr.columbia.edu>

41 __FBSDID("$FreeBSD$");
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.
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:
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
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.
73 * Note that some PCMCIA controller software packages for Windows NT
74 * fail to set the voltages as well.
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.
