- 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.

- 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.
+ This will disable DMA and always enable PIO instead.
