Looks like I managed to not actually commit the move of the field to the
head of the struct! v3.1 follows....

Subject: [PATCH] net/designware: reorder struct dw_eth_dev to pack more
 efficiently.

The {tx,rx}_mac_descrtable fields are aligned to ARCH_DMA_MINALIGN, which could
be 256 or even larger. That means there is a potentially huge hole in the
struct before those fields, so move them to the front where they are better
packed.

Moving them to the front also helps ensure that so long as dw_eth_dev is
properly aligned (which it is since "net/designware: ensure device private data
is DMA aligned.") the {tx,rx}_mac_descrtable will be too, or at least avoids
having to worry too much about compiler specifics.

The {r,t}xbuffs fields also need to be aligned. Previously this was done
implicitly because they immediately followed the descriptor tables. Make this
explicit and also move to the head of the struct.
