Christof Schmitt	1674b40547	[SCSI] zfcp: Move sbale handling to zfcp_qdio files ... Move the code accessing the qdio sbales and zfcp_qdio_req struct to the zfcp_qdio files and provide helper functions for accessing the qdio related parts.

Christof Schmitt	683229845f	[SCSI] zfcp: Report scatter-gather limits to SCSI and block layer ... Instead of dealing with large segments in the scatter-gather lists in zfcp_qdio.c, report the limits to the upper layers. With these limits in place, the code for mapping large data blocks to multiple sbales can be removed.

Christof Schmitt	34c2b71299	[SCSI] zfcp: Introduce header file for qdio structs and inline functions ... Move the qdio related structs and some helper functions to a new zfcp_qdio.h header file. While doing this, rename the struct zfcp_queue_req to zfcp_qdio_req to adhere to the naming scheme used in zfcp. This allows a better seperation of the qdio code and inlining the helper functions will save some function calls.
