   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.

  65           Say Y, because this information will help you get the driver running.

  86           Include both, Direct Memory Access (DMA) and Programmed I/O (PIO)
  87           data transfer modes. The mode actually used is selectable through
  88           the module parameter "pio". With pio=0 as a module parameter, the
  89           default DMA is used, otherwise PIO is used.
  90
  91           If unsure, choose this option.

  96         ---help---
  97           Only include Direct Memory Access (DMA).
  98           This reduces the size of the driver module, by omitting the PIO code.
  99
 100 config B43LEGACY_PIO_MODE
 101         bool "PIO (Programmed I/O) only"
 102         select B43LEGACY_PIO

 104           Only include Programmed I/O (PIO).
 105           This reduces the size of the driver module, by omitting the DMA code.
 106           Please note that PIO transfers are slow (compared to DMA).
 107
 108           Also note that not all devices of the b43legacy series support PIO.
 109
 110           You should use PIO only if DMA does not work for you.
