   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.

  82           Please note that most PC-CARD devices are _NOT_ 16bit PCMCIA
  83           devices, but 32bit CardBUS devices. CardBUS devices are supported
  84           out of the box by b43.

  88           CF b43 cards can sometimes be found in handheld PCs.

 198           This adds additional runtime sanity checks and statistics to the driver.
 199           These checks and statistics might be expensive and hurt the runtime
 200           performance of your system.
 201           This also adds the b43 debugfs interface.
 202
 203           Do not enable this, unless you are debugging the driver.

 205           Say N, if you are a distributor or user building a release kernel
