b43 is a driver for the Broadcom 43xx series wireless devices.
Check "lspci" for something like
"Broadcom Corporation BCM43XX 802.11 Wireless LAN Controller"
to determine whether you own such a device.
This driver supports the new BCM43xx IEEE 802.11G devices, but not
the old IEEE 802.11B devices. Old devices are supported by
the b43legacy driver.
Note that this has nothing to do with the standard that your AccessPoint
supports ([31mCONFIG_A[0m, [31mCONFIG_B[0m, [31mCONFIG_G[0m or a combination).
IEEE 802.11G devices can talk to IEEE 802.11B AccessPoints.
It is safe to include both b43 and b43legacy as the underlying glue
layer will automatically load the correct version for your device.
This driver uses V4 firmware, which must be installed separately using
b43-fwcutter.
This driver can be built as a module (recommended) that will be called "b43".
If unsure, say [31mCONFIG_M[0m.

Broadcom 43xx device support for Soft-[31mCONFIG_MAC[0m SDIO devices.
With this config option you can drive Soft-[31mCONFIG_MAC[0m b43 cards with a
Secure Digital I/O interface.
This includes the [31mCONFIG_WLAN[0m daughter card found on the Nintendo Wii
video game console.
Note that this does not support Broadcom 43xx Full-[31mCONFIG_MAC[0m devices.
It's safe to select Y here, even if you don't have a [31mCONFIG_B43[0m SDIO device.

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