	  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.

	  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.
