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.

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.

Support for the LP-PHY.
|
|
The LP-PHY is a low-power PHY built into some notebooks

and embedded devices. It supports 802.11a/g
|

(802.11a support is optional, and currently disabled).

Broadcom 43xx debugging.
|
|
|
|
This adds additional runtime sanity checks and statistics to the driver.
|
|
These checks and statistics might me expensive and hurt 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.

This will disable DMA and always enable PIO instead.

Say N!
|

This is only for debugging the PIO engine code. You do
|

_NOT_ want to enable this.
