   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.

  50           Broadcom 43xx PCMCIA device support.
  51
  52           Support for 16bit PCMCIA devices.
  53           Please note that most PC-CARD devices are _NOT_ 16bit PCMCIA
  54           devices, but 32bit CardBUS devices. CardBUS devices are supported
  55           out of the box by b43.
  56
  57           With this config option you can drive b43 cards in
  58           CompactFlash formfactor in a PCMCIA adaptor.
  59           CF b43 cards can sometimes be found in handheld PCs.
  60
  61           It's safe to select Y here, even if you don't have a B43 PCMCIA device.

  63           If unsure, say N.

  87           Support for the LP-PHY.

  89           and embedded devices.

 114
 115           This adds additional runtime sanity checks and statistics to the driver.
 116           These checks and statistics might me expensive and hurt runtime performance
 117           of your system.
 118           This also adds the b43 debugfs interface.
 119
 120           Do not enable this, unless you are debugging the driver.
 121
 122           Say N, if you are a distributor or user building a release kernel
 123           for production use.
 124           Only say Y, if you are debugging a problem in the b43 driver sourcecode.

 128         depends on B43 && B43_DEBUG
 129         ---help---
 130           This will disable DMA and always enable PIO instead.
 131
 132           Say N!
 133           This is only for debugging the PIO engine code. You do
 134           _NOT_ want to enable this.
