This is important patch for new devices that support unaligned
addressing. That devices suffer from the backward-compatibility bug in
DMA engine. In theory we should be able to use old mechanism, but in
practice DMA address seems to be randomly copied into status register
when hardware reaches end of a ring. This breaks reading slot number
from status register and we can't use DMA anymore.

This makes it possible to use swconfig to controll the switch.
This was tested with devices using b43 and bgmac.
This was not tested on devices using tg3.
This does not support the adm switch used in some very old devices.
