7 b43 is a driver for the Broadcom 43xx series wireless devices.
8
9 Check "lspci" for something like
10 "Broadcom Corporation BCM43XX 802.11 Wireless LAN Controller"
11 to determine whether you own such a device.
12
13 This driver supports the new BCM43xx IEEE 802.11G devices, but not
14 the old IEEE 802.11B devices. Old devices are supported by
15 the b43legacy driver.
16 Note that this has nothing to do with the standard that your AccessPoint
17 supports (A, B, G or a combination).
18 IEEE 802.11G devices can talk to IEEE 802.11B AccessPoints.
19
20 It is safe to include both b43 and b43legacy as the underlying glue
21 layer will automatically load the correct version for your device.
22
23 This driver uses V4 firmware, which must be installed separately using
24 b43-fwcutter.
25
26 This driver can be built as a module (recommended) that will be called "b43".
27 If unsure, say M.

57 select SSB_PCMCIAHOST
58 ---help---
59 Broadcom 43xx PCMCIA device support.
60
61 Support for 16bit PCMCIA devices.
62 Please note that most PC-CARD devices are _NOT_ 16bit PCMCIA
63 devices, but 32bit CardBUS devices. CardBUS devices are supported
64 out of the box by b43.
65
66 With this config option you can drive b43 cards in
67 CompactFlash formfactor in a PCMCIA adaptor.
68 CF b43 cards can sometimes be found in handheld PCs.
69
70 It's safe to select Y here, even if you don't have a B43 PCMCIA device.
71
72 If unsure, say N.

78 ---help---
79 Broadcom 43xx device support for Soft-MAC SDIO devices.
80
81 With this config option you can drive Soft-MAC b43 cards with a
82 Secure Digital I/O interface.
83 This includes the WLAN daughter card found on the Nintendo Wii
84 video game console.
85 Note that this does not support Broadcom 43xx Full-MAC devices.
86
87 It's safe to select Y here, even if you don't have a B43 SDIO device.
88
89 If unsure, say N.

110 Support for the N-PHY.
111
112 This enables support for devices with N-PHY.
113
114 Say N if you expect high stability and performance. Saying Y will not
115 affect other devices support and may provide support for basic needs.
116
117config B43_PHY_LP
118 bool "Support for low-power (LP-PHY) devices"
119 depends on B43
120 default y
121 ---help---
122 Support for the LP-PHY.
123 The LP-PHY is a low-power PHY built into some notebooks
124 and embedded devices. It supports 802.11a/b/g
125 (802.11a support is optional, and currently disabled).
126

132 Support for the HT-PHY.
133
134 Enables support for BCM4331 and possibly other chipsets with that PHY.
135
136config B43_PHY_LCN
137 bool "Support for LCN-PHY devices (BROKEN)"
138 depends on B43 && BROKEN

162 Broadcom 43xx debugging.
163
164 This adds additional runtime sanity checks and statistics to the driver.
165 These checks and statistics might be expensive and hurt the runtime
166 performance of your system.
167 This also adds the b43 debugfs interface.
168
169 Do not enable this, unless you are debugging the driver.
170
171 Say N, if you are a distributor or user building a release kernel
172 for production use.
173 Only say Y, if you are debugging a problem in the b43 driver sourcecode.
