- This is an experimental driver for the Broadcom 43xx wireless chip,

- Broadcom 43xx PCI device support.
-
- Say Y, if you have a BCM43xx device connected through the PCI bus.
- Please note that most PC-CARD devices are (to the kernel) PCI devices,
- too and not PCMCIA.
- It's safe to select Y here, even if you don't have a BCM43xx PCI device.
-

- 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
- by "BCM43xx PCI device support".
-
- With this config option you can drive bcm43xx cards in
- CompactFlash formfactor in a PCMCIA adaptor.
- CF bcm43xx cards can sometimes be found in handheld PCs.
-
- It's safe to select Y here, even if you don't have a BCM43xx PCMCIA device.
-
- If unsure, say N.
-

- depends on BCM43XX_MAC80211
- select SSB_DEBUG if !SSB_SILENT
- default y
- ---help---

- Say Y, because the driver is still very experimental and
- this will help you get it running.

- 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.
-

- Only include Direct Memory Access (DMA).
- This reduces the size of the driver module, by omitting the PIO code.
-

- bool "PIO (Programmed I/O) only"
- select BCM43XX_MAC80211_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.
