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

75 bool "Broadcom 43xx PCMCIA device support"
76 depends on B43 && B43_SSB && SSB_PCMCIAHOST_POSSIBLE
79 Broadcom 43xx PCMCIA device support.
81 Support for 16bit PCMCIA devices.
82 Please note that most PC-CARD devices are _NOT_ 16bit PCMCIA
83 devices, but 32bit CardBUS devices. CardBUS devices are supported
84 out of the box by b43.
86 With this config option you can drive b43 cards in
87 CompactFlash formfactor in a PCMCIA adaptor.
88 CF b43 cards can sometimes be found in handheld PCs.
90 It's safe to select Y here, even if you don't have a B43 PCMCIA device.
95 bool "Broadcom 43xx SDIO device support"
96 depends on B43 && B43_SSB && SSB_SDIOHOST_POSSIBLE
99 Broadcom 43xx device support for Soft-MAC SDIO devices.
101 With this config option you can drive Soft-MAC b43 cards with a
102 Secure Digital I/O interface.
103 This includes the WLAN daughter card found on the Nintendo Wii
105 Note that this does not support Broadcom 43xx Full-MAC devices.
107 It's safe to select Y here, even if you don't have a B43 SDIO device.

126 bool "Support for 802.11n (N-PHY) devices"
130 Support for the N-PHY.
132 This enables support for devices with N-PHY.
134 Say N if you expect high stability and performance. Saying Y will not
135 affect other devices support and may provide support for basic needs.
138 bool "Support for low-power (LP-PHY) devices"
139 depends on B43 && B43_SSB
142 Support for the LP-PHY.
143 The LP-PHY is a low-power PHY built into some notebooks
144 and embedded devices. It supports 802.11a/b/g
145 (802.11a support is optional, and currently disabled).
148 bool "Support for HT-PHY (high throughput) devices"
149 depends on B43 && B43_BCMA
152 Support for the HT-PHY.
154 Enables support for BCM4331 and possibly other chipsets with that PHY.
157 bool "Support for LCN-PHY devices (BROKEN)"
158 depends on B43 && BROKEN
160 Support for the LCN-PHY.
162 Say N, this is BROKEN and crashes driver.

179 bool "Broadcom 43xx debugging"
182 Broadcom 43xx debugging.
184 This adds additional runtime sanity checks and statistics to the driver.
185 These checks and statistics might be expensive and hurt the runtime
186 performance of your system.
187 This also adds the b43 debugfs interface.
189 Do not enable this, unless you are debugging the driver.
191 Say N, if you are a distributor or user building a release kernel
193 Only say Y, if you are debugging a problem in the b43 driver sourcecode.
