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.

49 Broadcom 43xx PCMCIA device support.
50
51 Support for 16bit PCMCIA devices.
52 Please note that most PC-CARD devices are _NOT_ 16bit PCMCIA
53 devices, but 32bit CardBUS devices. CardBUS devices are supported
54 out of the box by b43.
55
56 With this config option you can drive b43 cards in
57 CompactFlash formfactor in a PCMCIA adaptor.
58 CF b43 cards can sometimes be found in handheld PCs.

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

70
71 With this config option you can drive Soft-MAC b43 cards with a
72 Secure Digital I/O interface.
73 This includes the WLAN daughter card found on the Nintendo Wii
74 video game console.
75 Note that this does not support Broadcom 43xx Full-MAC devices.

Michael Buesch060210f2009-01-25 15:49:59 +0100130 This adds additional runtime sanity checks and statistics to the driver.
131 These checks and statistics might me expensive and hurt runtime performance
132 of your system.
133 This also adds the b43 debugfs interface.
134
135 Do not enable this, unless you are debugging the driver.
136
137 Say N, if you are a distributor or user building a release kernel
138 for production use.
139 Only say Y, if you are debugging a problem in the b43 driver sourcecode.
