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. Signed-off-by: Krzysztof Halasa <khc@pm.waw.pl> Acked-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: David S.
