| 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. | |
| If unsure, choose this option. | |

| Only include Direct Memory Access (DMA). | |
| This reduces the size of the driver module, by omitting the PIO code. | |

| bool "PIO (Programmed I/O) only" | |
| select BCM43XX_PIO | |
| ---help--- | |
| 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. | |
