- b43legacy is a driver for 802.11b devices from Broadcom (BCM4301 and
- BCM4303) and early model 802.11g chips (BCM4306 Ver. 2) used in the
- Linksys WPC54G V1 PCMCIA devices.
- Newer 802.11g and 802.11a devices need b43.
- 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 V3 firmware, which must be installed separately using
- b43-fwcutter.
- This driver can be built as a module (recommended) that will be
- called "b43legacy". If unsure, say M.

- ---help---
- Include both, Direct Memory Access (DMA) and Programmed I/O (PIO)
- data transfer modes. The mode actually used is selectable through
- the module parameter "pio". With pio=0 as a module parameter, the
- default DMA is used, otherwise PIO is used.
- If unsure, choose this option.
- config B43LEGACY_DMA_MODE
- bool "DMA (Direct Memory Access) only"
- select B43LEGACY_DMA
- ---help---
- Only include Direct Memory Access (DMA).
- This reduces the size of the driver module, by omitting the PIO code.
- config B43LEGACY_PIO_MODE
- bool "PIO (Programmed I/O) only"
- select B43LEGACY_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 b43legacy series support PIO.
- You should use PIO only if DMA does not work for you.
