2 tristate "Broadcom BCM43xx wireless support (DEPRECATED)"
3 depends on PCI && IEEE80211 && IEEE80211_SOFTMAC && WLAN_80211 && EXPERIMENTAL
8 This is an experimental driver for the Broadcom 43xx wireless
9 chip, found in the Apple Airport Extreme and various other
10 devices. This driver is deprecated and will be removed
11 from the kernel in the near future. It has been replaced
12 by the b43 and b43legacy drivers.
15 bool "Broadcom BCM43xx debugging (RECOMMENDED)"
19 Broadcom 43xx debugging messages.
20 Say Y, because the driver is still very experimental and
21 this will help you get it running.
32 prompt "BCM43xx data transfer mode"
34 default BCM43XX_DMA_AND_PIO_MODE
36 config BCM43XX_DMA_AND_PIO_MODE
41 Include both, Direct Memory Access (DMA) and Programmed I/O (PIO)
43 The actually used mode is selectable through the module
44 parameter "pio". If the module parameter is pio=0, DMA is used.
45 Otherwise PIO is used. DMA is default.
47 If unsure, choose this option.
49 config BCM43XX_DMA_MODE
50 bool "DMA (Direct Memory Access) only"
53 Only include Direct Memory Access (DMA).
54 This reduces the size of the driver module, by omitting the PIO code.
56 config BCM43XX_PIO_MODE
57 bool "PIO (Programmed I/O) only"
60 Only include Programmed I/O (PIO).
61 This reduces the size of the driver module, by omitting the DMA code.
62 Please note that PIO transfers are slow (compared to DMA).
64 Also note that not all devices of the 43xx series support PIO.
65 The 4306 (Apple Airport Extreme and others) supports PIO, while
66 the 4318 is known to _not_ support PIO.
68 Only use PIO, if DMA does not work for you.
