My current code allows the submitter to specify which tags are valid between the OS and the HBA. Your inbound scsi_cmnd will have a protection_tag_mask which tells you which fields are provided. Similarly, there's a mask in scsi_host which allows the HBA to identify which protection types it supports. I hadn't envisioned that an HBA might only provide a subset. I'll ponder a bit.

In other words you only support one app tag per request and not per sector? -- Martin K.
