	  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.

# Auto-select SSB PCI-HOST support, if possible

config B43_PCMCIA
	bool "Broadcom 43xx PCMCIA device support (EXPERIMENTAL)"
	depends on B43 && SSB_PCMCIAHOST_POSSIBLE && EXPERIMENTAL
	select SSB_PCMCIAHOST
	---help---
	  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.

	  Broadcom 43xx debugging messages.

	  Say Y, if you want to find out why the driver does not
	  work for you.

config B43_DMA_AND_PIO_MODE
	bool "DMA + PIO"
	select B43_DMA
	select B43_PIO
	---help---
	  Include both, Direct Memory Access (DMA) and Programmed I/O (PIO)
	  data transfer modes.
	  The actually used mode is selectable through the module
	  parameter "pio". If the module parameter is pio=0, DMA is used.
	  Otherwise PIO is used. DMA is default.

	  If unsure, choose this option.

config B43_DMA_MODE
	bool "DMA (Direct Memory Access) only"
	select B43_DMA
	---help---
	  Only include Direct Memory Access (DMA).
	  This reduces the size of the driver module, by omitting the PIO code.

config B43_PIO_MODE
	bool "PIO (Programmed I/O) only"
	select B43_PIO
	---help---
	  Only include Programmed I/O (PIO).
	  This reduces the size of the driver module, by omitting the DMA code.
	  Please note that PIO transfers are slow (compared to DMA).

	  Also note that not all devices of the 43xx series support PIO.
	  The 4306 (Apple Airport Extreme and others) supports PIO, while
	  the 4318 is known to _not_ support PIO.

	  Only use PIO, if DMA does not work for you.
