	  b43 is a driver for the Broadcom 43xx series wireless devices.

	  Check "lspci" for something like
	  "Broadcom Corporation BCM43XX 802.11 Wireless LAN Controller"
	  to determine whether you own such a device.

	  This driver supports the new BCM43xx IEEE 802.11G devices, but not
	  the old IEEE 802.11B devices. Old devices are supported by
	  the b43legacy driver.
	  Note that this has nothing to do with the standard that your AccessPoint
	  supports (A, B, G or a combination).
	  IEEE 802.11G devices can talk to IEEE 802.11B AccessPoints.

	  It is safe to include both b43 and b43legacy as the underlying glue
	  layer will automatically load the correct version for your device.

	  This driver uses V4 firmware, which must be installed separately using
	  b43-fwcutter.

	  This driver can be built as a module (recommended) that will be called "b43".
	  If unsure, say M.

	  Broadcom 43xx PCMCIA device support.

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

	  With this config option you can drive b43 cards in
	  CompactFlash formfactor in a PCMCIA adaptor.
	  CF b43 cards can sometimes be found in handheld PCs.

	  It's safe to select Y here, even if you don't have a B43 PCMCIA device.

	  If unsure, say N.

	select SSB_SDIOHOST
	---help---
	  Broadcom 43xx device support for Soft-MAC SDIO devices.

	  With this config option you can drive Soft-MAC b43 cards with a
	  Secure Digital I/O interface.
	  This includes the WLAN daughter card found on the Nintendo Wii
	  video game console.
	  Note that this does not support Broadcom 43xx Full-MAC devices.

	  It's safe to select Y here, even if you don't have a B43 SDIO device.

	  If unsure, say N.

	bool "Support for 802.11n (N-PHY) devices"

	default y
	---help---
	  Support for the N-PHY.

	  This enables support for devices with N-PHY.

	  Say N if you expect high stability and performance. Saying Y will not
	  affect other devices support and may provide support for basic needs.

config B43_PHY_LP
	bool "Support for low-power (LP-PHY) devices"
	depends on B43 && B43_SSB
	default y
	---help---
	  Support for the LP-PHY.
	  The LP-PHY is a low-power PHY built into some notebooks
	  and embedded devices. It supports 802.11a/b/g
	  (802.11a support is optional, and currently disabled).

config B43_PHY_HT
	bool "Support for HT-PHY (high throughput) devices"
	depends on B43 && B43_BCMA
	default y
	---help---
	  Support for the HT-PHY.

	  Enables support for BCM4331 and possibly other chipsets with that PHY.

config B43_PHY_LCN
	bool "Support for LCN-PHY devices (BROKEN)"
	depends on B43 && BROKEN
	---help---
	  Support for the LCN-PHY.

	  Say N, this is BROKEN and crashes driver.

config B43_DEBUG
	bool "Broadcom 43xx debugging"
	depends on B43
	---help---
	  Broadcom 43xx debugging.

	  This adds additional runtime sanity checks and statistics to the driver.
	  These checks and statistics might be expensive and hurt the runtime
	  performance of your system.
	  This also adds the b43 debugfs interface.

	  Do not enable this, unless you are debugging the driver.

	  Say N, if you are a distributor or user building a release kernel
	  for production use.
	  Only say Y, if you are debugging a problem in the b43 driver sourcecode.
