This patch introduces BIP_CHECK_GUARD/REFTAG/APPTAG bip_flags which
indicate how the hardware should check the integrity payload.
BIP_CHECK_GUARD/REFTAG are conversion of existing semantics, while
BIP_CHECK_APPTAG is a new flag. The driver can now just rely on block
layer flags, and doesn't need to know the integrity source. Submitter
of PI decides which tags to check. This would also give us a unified
interface for user and kernel generated integrity.

Looks good.
