config BCM43XX
tristate "Broadcom BCM43xx wireless support"
depends on PCI && IEEE80211 && IEEE80211_SOFTMAC && NET_RADIO && EXPERIMENTAL
select FW_LOADER
---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.
config BCM43XX_DMA
bool
depends on BCM43XX
config BCM43XX_PIO
bool
depends on BCM43XX
choice
prompt "BCM43xx data transfer mode"
depends on BCM43XX
default BCM43XX_DMA_AND_PIO_MODE
config BCM43XX_DMA_AND_PIO_MODE
bool "DMA + PIO"
select BCM43XX_DMA
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.
