| Say Y, because the driver is still very experimental and |

| 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. |

| config BCM43XX_DMA_MODE |

| select BCM43XX_DMA |
| ---help--- |
| Only include Direct Memory Access (DMA). |
| This reduces the size of the driver module, by omitting the PIO code. |
| |
| config BCM43XX_PIO_MODE |
| 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. |
