7 b43legacy is a driver for 802.11b devices from Broadcom (BCM4301 and
8 BCM4303) and early model 802.11g chips (BCM4306 Ver. 2) used in the
9 Linksys WPC54G V1 PCMCIA devices.
11 Newer 802.11g and 802.11a devices need b43.
13 It is safe to include both b43 and b43legacy as the underlying glue
14 layer will automatically load the correct version for your device.
16 This driver uses V3 firmware, which must be installed separately using
19 This driver can be built as a module (recommended) that will be
20 called "b43legacy". If unsure, say M.

52 config B43LEGACY_DEBUG
53 bool "Broadcom 43xx-legacy debugging"
57 Say Y, because this information will help you get the driver running.
58 This option generates a minimum of log output.
69 prompt "Broadcom 43xx-legacy data transfer mode"
71 default B43LEGACY_DMA_AND_PIO_MODE
73 config B43LEGACY_DMA_AND_PIO_MODE
78 Include both, Direct Memory Access (DMA) and Programmed I/O (PIO)
79 data transfer modes. The mode actually used is selectable through
80 the module parameter "pio". With pio=0 as a module parameter, the
81 default DMA is used, otherwise PIO is used.
83 If unsure, choose this option.
85 config B43LEGACY_DMA_MODE
86 bool "DMA (Direct Memory Access) only"
89 Only include Direct Memory Access (DMA).
90 This reduces the size of the driver module, by omitting the PIO code.
92 config B43LEGACY_PIO_MODE
93 bool "PIO (Programmed I/O) only"
96 Only include Programmed I/O (PIO).
97 This reduces the size of the driver module, by omitting the DMA code.
98 Please note that PIO transfers are slow (compared to DMA).
100 Also note that not all devices of the b43legacy series support PIO.
102 You should use PIO only if DMA does not work for you.
