0010 b43 is a driver for the Broadcom 43xx series wireless devices.
0011
0012 Check "lspci" for something like
0013 "Broadcom Corporation BCM43XX 802.11 Wireless LAN Controller"
0014 to determine whether you own such a device.
0015
0016 This driver supports the new BCM43xx IEEE 802.11G devices, but not
0017 the old IEEE 802.11B devices. Old devices are supported by
0018 the b43legacy driver.
0019 Note that this has nothing to do with the standard that your AccessPoint
0020 supports (A, B, G or a combination).
0021 IEEE 802.11G devices can talk to IEEE 802.11B AccessPoints.
0022
0023 It is safe to include both b43 and b43legacy as the underlying glue
0024 layer will automatically load the correct version for your device.
0025
0026 This driver uses V4 firmware, which must be installed separately using
0027 b43-fwcutter.
0028
0029 This driver can be built as a module (recommended) that will be called "b43".
0030 If unsure, say M.

0180 This adds additional runtime sanity checks and statistics to the driver.
0181 These checks and statistics might be expensive and hurt the runtime
0182 performance of your system.
0183 This also adds the b43 debugfs interface.
0184
0185 Do not enable this, unless you are debugging the driver.
0186
0187 Say N, if you are a distributor or user building a release kernel
0188 for production use.
0189 Only say Y, if you are debugging a problem in the b43 driver sourcecode.
