[PATCH 3/6] async_tx: Handle DMA devices having support for fewer PQ coefficients

2017-02-01 Thread Anup Patel
The DMAENGINE framework assumes that if PQ offload is supported by a DMA device then all 256 PQ coefficients are supported. This assumption does not hold anymore because we now have BCM-SBA-RAID offload engine which supports PQ offload with limited number of PQ coefficients. This patch extends
