   7          b43 is a driver for the Broadcom 43xx series wireless devices.
   8
   9          Check "lspci" for something like
  10          "Broadcom Corporation BCM43XX 802.11 Wireless LAN Controller"
  11          to determine whether you own such a device.
  12
  13          This driver supports the new BCM43xx IEEE 802.11G devices, but not
  14          the old IEEE 802.11B devices. Old devices are supported by
  15          the b43legacy driver.
  16          Note that this has nothing to do with the standard that your AccessPoint
  17          supports (A, B, G or a combination).
  18          IEEE 802.11G devices can talk to IEEE 802.11B AccessPoints.
  19
  20          It is safe to include both b43 and b43legacy as the underlying glue
  21          layer will automatically load the correct version for your device.
  22
  23          This driver uses V4 firmware, which must be installed separately using
  24          b43-fwcutter.
  25
  26          This driver can be built as a module (recommended) that will be called "b43".
  27          If unsure, say M.

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

  69          Broadcom 43xx device support for Soft-MAC SDIO devices.
  70
  71          With this config option you can drive Soft-MAC b43 cards with a
  72          Secure Digital I/O interface.
  73          This includes the WLAN daughter card found on the Nintendo Wii
  74          video game console.
  75          Note that this does not support Broadcom 43xx Full-MAC devices.
  76
  77          It's safe to select Y here, even if you don't have a B43 SDIO device.
  78
  79          If unsure, say N.

 103        ---help---
 104          Support for the LP-PHY.
 105          The LP-PHY is a low-power PHY built into some notebooks
 106          and embedded devices. It supports 802.11a/g
 107          (802.11a support is optional, and currently disabled).

 128
 129          This adds additional runtime sanity checks and statistics to the driver.
 130          These checks and statistics might me expensive and hurt runtime performance
 131          of your system.
 132          This also adds the b43 debugfs interface.
 133
 134          Do not enable this, unless you are debugging the driver.
 135
 136          Say N, if you are a distributor or user building a release kernel
 137          for production use.
 138          Only say Y, if you are debugging a problem in the b43 driver sourcecode.

 144          This will disable DMA and always enable PIO instead.
 145
 146          Say N!
 147          This is only for debugging the PIO engine code. You do
 148          _NOT_ want to enable this.
