E100: work around the driver using streaming DMA mapping for RX descriptors.
E100 places it's RX packet descriptors inside skb->data and uses them
with bidirectional streaming DMA mapping. Unfortunately it fails to
transfer skb->data ownership to the device after it reads the
descriptor's status, breaking on non-coherent (e.g., ARM) platforms.
This have to be converted to use coherent memory for the descriptors.
