nab> pi_prot_version: Protection Version (DIF v1 currently supported)
What's DIF v2?
nab> pi_guard_type: Guard Type (1=DIF CRC, 2=IP CRC)
The IP checksum is only supported by DIX between OS and initiator, not
by the target. I guess we could signal to the initiator via a
vendor-private VPD that IP checksum is supported directly. But now what
we have hardware-accelerated T10 CRC I don't think it's a big deal.
shouldn't it stick around if it is not deprecated yet, the transport is
required to support ip-csum->CRC conversion anyhow.
(scsi_debug supports IP checksum because it's both initiator and
target).
