   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.

  63         select SSB_PCMCIAHOST
  64         ---help---
  65           Broadcom 43xx PCMCIA device support.
  66
  67           Support for 16bit PCMCIA devices.
  68           Please note that most PC-CARD devices are _NOT_ 16bit PCMCIA
  69           devices, but 32bit CardBUS devices. CardBUS devices are supported
  70           out of the box by b43.
  71
  72           With this config option you can drive b43 cards in
  73           CompactFlash formfactor in a PCMCIA adaptor.
  74           CF b43 cards can sometimes be found in handheld PCs.
  75
  76           It's safe to select Y here, even if you don't have a B43 PCMCIA device.
  77
  78           If unsure, say N.

  84         ---help---
  85           Broadcom 43xx device support for Soft-MAC SDIO devices.
  86
  87           With this config option you can drive Soft-MAC b43 cards with a
  88           Secure Digital I/O interface.
  89           This includes the WLAN daughter card found on the Nintendo Wii
  90           video game console.
  91           Note that this does not support Broadcom 43xx Full-MAC devices.
  92
  93           It's safe to select Y here, even if you don't have a B43 SDIO device.
  94
  95           If unsure, say N.

 114         ---help---
 115           Support for the N-PHY.
 116
 117           This enables support for devices with N-PHY.
 118
 119           Say N if you expect high stability and performance. Saying Y will not
 120           affect other devices support and may provide support for basic needs.
 121
 122 config B43_PHY_LP
 123         bool "Support for low-power (LP-PHY) devices"
 124         depends on B43
 125         default y
 126         ---help---
 127           Support for the LP-PHY.
 128           The LP-PHY is a low-power PHY built into some notebooks
 129           and embedded devices. It supports 802.11a/b/g
 130           (802.11a support is optional, and currently disabled).
 131
 132 config B43_PHY_HT

 134         depends on B43
 135         ---help---
 136           Support for the HT-PHY.
 137
 138           Enables support for BCM4331 and possibly other chipsets with that PHY.
 139
 140 config B43_PHY_LCN

 142         depends on B43 && BROKEN
 143         ---help---
 144           Support for the LCN-PHY.
 145
 146           Say N, this is BROKEN and crashes driver.
 147

 149 # if it's possible.

 164         depends on B43
 165         ---help---
 166           Broadcom 43xx debugging.
 167
 168           This adds additional runtime sanity checks and statistics to the driver.
 169           These checks and statistics might me expensive and hurt runtime performance
 170           of your system.
 171           This also adds the b43 debugfs interface.
 172
 173           Do not enable this, unless you are debugging the driver.
 174
 175           Say N, if you are a distributor or user building a release kernel
 176           for production use.
 177           Only say Y, if you are debugging a problem in the b43 driver sourcecode.
