This is an experimental driver for the Broadcom 43xx wireless
|
|
|
|
|
chip, found in the Apple Airport Extreme and various other
|
|
|
|
|
devices. This driver is deprecated and will be removed
|
|
|
|
|
from the kernel in the near future. It has been replaced
|
|
|
|
|
by the b43 and b43legacy drivers.

this will help you get it running.

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.

|
|
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.
|
|
|
|
|
|
2006-02-12 23:47:44 +08:00
|
|
|
Only use PIO, if DMA does not work for you.
