  7	  b43legacy is a driver for 802.11b devices from Broadcom (BCM4301 and
  8	  BCM4303) and early model 802.11g chips (BCM4306 Ver. 2) used in the
  9	  Linksys WPC54G V1 PCMCIA devices.
 10
 11	  Newer 802.11g and 802.11a devices need b43.
 12
 13	  It is safe to include both b43 and b43legacy as the underlying glue
 14	  layer will automatically load the correct version for your device.
 15
 16	  This driver uses V3 firmware, which must be installed separately using
 17	  b43-fwcutter.
 18
 19	  This driver can be built as a module (recommended) that will be
 20	  called "b43legacy". If unsure, say M.

 77	---help---
 78	  Include both, Direct Memory Access (DMA) and Programmed I/O (PIO)
 79	  data transfer modes. The mode actually used is selectable through
 80	  the module parameter "pio". With pio=0 as a module parameter, the
 81	  default DMA is used, otherwise PIO is used.
 82
 83	  If unsure, choose this option.
 84
 85config B43LEGACY_DMA_MODE
 86	bool "DMA (Direct Memory Access) only"
 87	select B43LEGACY_DMA
 88	---help---
 89	  Only include Direct Memory Access (DMA).
 90	  This reduces the size of the driver module, by omitting the PIO code.
 91
 92config B43LEGACY_PIO_MODE
 93	bool "PIO (Programmed I/O) only"
 94	select B43LEGACY_PIO
 95	---help---
 96	  Only include Programmed I/O (PIO).
 97	  This reduces the size of the driver module, by omitting the DMA code.
 98	  Please note that PIO transfers are slow (compared to DMA).
 99
100	  Also note that not all devices of the b43legacy series support PIO.
101
102	  You should use PIO only if DMA does not work for you.
