Message

This patchset introduces support to the driver for DIF/DIX (or PI -
protection information).

We will only support PI in v3 hw at the moment, even though previous hw
versions also support it.

The series is broken down as follows:
- Tidy sg table size config
- Some tidy-up to accept PI support
- Add components for PI support for main and v3 driver

Difference v1->v2:
- drop scsi_prot_op_normal()

Xiang Chen (3):
  scsi: hisi_sas: Relocate some code to reduce complexity
  scsi: hisi_sas: Make sg_tablesize consistent value
  scsi: hisi_sas: Add support for DIF/DIX feature for v3 hw
