The Marvell mv643xx ethernet hardware requires that DMA buffers be
aligned to 8-byte boundaries. This patch satisfies this requirement.
Buffers allocated by dev_alloc_skb() only have 4-byte alignment when
slab debugging is enabled.
Also, document that the 2-byte offset to align the IP packets on
receive is a hardware feature and is not tied to NET_IP_ALIGN.

If you do a dma_map_single you must do dma_unmap_single and if you do
a dma_map_page you must do a dma_unmap_page.
