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

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