   8           b43 is a driver for the Broadcom 43xx series wireless devices.
   9
  10           Check "lspci" for something like
  11           "Broadcom Corporation BCM43XX 802.11 Wireless LAN Controller"
  12           to determine whether you own such a device.
  13
  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
  16           the b43legacy driver.
  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.
  20
  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.
  23
  24           This driver uses V4 firmware, which must be installed separately using
  25           b43-fwcutter.
  26
  27           This driver can be built as a module (recommended) that will be called "b43".
  28           If unsure, say M.

 178           This adds additional runtime sanity checks and statistics to the driver.
 179           These checks and statistics might be expensive and hurt the runtime
 180           performance of your system.
 181           This also adds the b43 debugfs interface.
 182
 183           Do not enable this, unless you are debugging the driver.
 184
 185           Say N, if you are a distributor or user building a release kernel
 186           for production use.
 187           Only say Y, if you are debugging a problem in the b43 driver sourcecode.
