[SCSI] Host protection capabilities
Controllers that support protection information must indicate this to
the SCSI midlayer so that the ULD can prepare scsi_cmnds accordingly.
This patch implements a host mask and various types of protection:
- DIF Type 1-3 (between HBA and disk)
- DIX Type 0-3 (between OS and HBA)
The patch also allows the HBA to set the guard type to something
different than the T10-mandated CRC.
