+Subject: [PATCH] dpaa_eth: base dma mappings on the fman rx port
+
+The dma transactions initiator is the rx fman port so that's the device
+that the dma mappings should be done. Previously the mappings were done
+through the MAC device which makes no sense because it's neither dma-able
+nor connected in any way to smmu.
