The bgmac driver will be used on the brcm47xx and the bcm53xx target.
These are only the patches already applied in current net-next/master
branch.

-bgmac: implement unaligned addressing for DMA rings that support it
-
-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.
