- ---help---
- This is an experimental driver for the Broadcom 43xx wireless chip,
- found in the Apple Airport Extreme and various other devices.
- config BCM43XX_DEBUG
- bool "Broadcom BCM43xx debugging (RECOMMENDED)"
- depends on BCM43XX
- default y
- ---help---
- Broadcom 43xx debugging messages.
- Say Y, because the driver is still very experimental and
- this will help you get it running.

- select BCM43XX_PIO
- ---help---
- Include both, Direct Memory Access (DMA) and Programmed I/O (PIO)
- data transfer modes.
- The actually used mode is selectable through the module
- parameter "pio". If the module parameter is pio=0, DMA is used.
- Otherwise PIO is used. DMA is default.
- If unsure, choose this option.
- config BCM43XX_DMA_MODE
- bool "DMA (Direct Memory Access) only"
- select BCM43XX_DMA
- ---help---
- Only include Direct Memory Access (DMA).
- This reduces the size of the driver module, by omitting the PIO code.
- config BCM43XX_PIO_MODE
- bool "PIO (Programmed I/O) only"
- select BCM43XX_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 43xx series support PIO.
- The 4306 (Apple Airport Extreme and others) supports PIO, while
- the 4318 is known to _not_ support PIO.
- Only use PIO, if DMA does not work for you.
