However, I would change the description: iSER has DMA alignment requirements that are too complex to express with q->dma_alignment. Therefore, if necessary, bouncing should be done by the iSER driver. Add a slave_configure function to set the alignment to zero, allowing the use of direct IO from arbitrary offsets within a page.
