b43 is a driver for the Broadcom 43xx series wireless devices.
9
Check "lspci" for something like
10
"Broadcom Corporation BCM43XX 802.11 Wireless LAN Controller"
11
to determine whether you own such a device.
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
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.
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.
23
This driver uses V4 firmware, which must be installed separately using
26
This driver can be built as a module (recommended) that will be called "b43".

bool "Broadcom 43xx PCMCIA device support"
46
depends on B43 && SSB_PCMCIAHOST_POSSIBLE
49
Broadcom 43xx PCMCIA device support.
51
Support for 16bit PCMCIA devices.
52
Please note that most PC-CARD devices are _NOT_ 16bit PCMCIA
53
devices, but 32bit CardBUS devices. CardBUS devices are supported
54
out of the box by b43.
56
With this config option you can drive b43 cards in
57
CompactFlash formfactor in a PCMCIA adaptor.
58
CF b43 cards can sometimes be found in handheld PCs.
60
It's safe to select Y here, even if you don't have a B43 PCMCIA device.
65
bool "Broadcom 43xx SDIO device support (EXPERIMENTAL)"
66
depends on B43 && SSB_SDIOHOST_POSSIBLE && EXPERIMENTAL
69
Broadcom 43xx device support for Soft-MAC SDIO devices.
71
With this config option you can drive Soft-MAC b43 cards with a
72
Secure Digital I/O interface.
73
This includes the WLAN daughter card found on the Nintendo Wii
75
Note that this does not support Broadcom 43xx Full-MAC devices.
77
It's safe to select Y here, even if you don't have a B43 SDIO device.

#Data transfers to the device via PIO. We want it as a fallback even
90
bool "Pre IEEE 802.11n support (BROKEN)"
91
depends on B43 && EXPERIMENTAL && BROKEN
93
Support for the IEEE 802.11n draft.
95
THIS IS BROKEN AND DOES NOT WORK YET.
100
bool "Support for low-power (LP-PHY) devices (EXPERIMENTAL)"
101
depends on B43 && EXPERIMENTAL
104
Support for the LP-PHY.
105
The LP-PHY is a low-power PHY built into some notebooks
106
and embedded devices. It supports 802.11a/g
107
(802.11a support is optional, and currently disabled).

bool "Broadcom 43xx debugging"
127
Broadcom 43xx debugging.
129
This adds additional runtime sanity checks and statistics to the driver.
130
These checks and statistics might me expensive and hurt runtime performance
132
This also adds the b43 debugfs interface.
134
Do not enable this, unless you are debugging the driver.
136
Say N, if you are a distributor or user building a release kernel
138
Only say Y, if you are debugging a problem in the b43 driver sourcecode.
141
bool "Force usage of PIO instead of DMA"
142
depends on B43 && B43_DEBUG
144
This will disable DMA and always enable PIO instead.
147
This is only for debugging the PIO engine code. You do
148
_NOT_ want to enable this.
