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.
