40 To compile this driver into the kernel,
41 place the following lines in your
42 kernel configuration file:
43 .Bd -ragged -offset indent
48 Alternatively, to load the driver as a
49 module at boot time, place the following line in
51 .Bd -literal -offset indent
57 driver provides support for Aironet Communications 4500 and 4800
58 wireless network adapters and variants, including the following:
60 .Bl -bullet -compact -offset indent
62 Aironet Communications 4500 and 4800 series
64 Cisco Aironet 340 and 350 series
66 Xircom Wireless Ethernet Adapter
69 Support for these devices include the ISA, PCI and PCMCIA
71 The Aironet 4500 series adapters operate at 1 and 2Mbps while
72 the Aironet 4800 series and Cisco adapters can operate at 1, 2, 5.5 and 11Mbps.
74 and PCMCIA devices are all based on the same core PCMCIA modules
75 and all have the same programming interface, however unlike the
76 Lucent WaveLAN/IEEE cards, the ISA and PCI cards appear to the
77 host as normal ISA and PCI devices and do not require any PCCARD
80 The PCMCIA Aironet cards require PC Card support, including the
84 ISA cards can either be configured to use ISA Plug and Play
85 or to use a particular I/O address and IRQ
86 by properly setting the DIP switches on the board.
88 switch setting is for Plug and Play.)
91 driver has Plug and Play support and will work in either configuration,
92 however when using a hard-wired I/O address and IRQ, the driver
93 configuration and the NIC's switch settings must agree.
95 require no switch settings of any kind and will be automatically
98 All host/device interaction with the Aironet cards is via programmed I/O.
99 The Aironet devices support 802.11 and 802.3 frames, power management,
100 BSS (infrastructure) and IBSS (ad-hoc) operation modes.
103 driver encapsulates all IP and ARP traffic as 802.11 frames, however
104 it can receive either 802.11 or 802.3 frames.
106 selectable between 1Mbps, 2Mbps, 5.5Mbps, 11Mbps or
107 "auto" (the NIC automatically chooses the best speed).
111 driver configures the Aironet card for infrastructure operation.
