Steffen,

> Since v2.6.35 commit 683229845f17 ("[SCSI] zfcp: Report scatter-gather
> limits to SCSI and block layer"), zfcp set dma_parms.max_segment_size ==
> PAGE_SIZE (but without using the setter dma_set_max_seg_size())
> and scsi_host_template.dma_boundary == PAGE_SIZE - 1.

Applied to 5.0/scsi-fixes, thank you!
