I don't think it does as people have pointed that out multiple times.
Once you do checksums on the device they are not end to end, either in
the T10 DIF definition or that of file system checksums.  You leave a
huge glaring gap in the protection envelope.  So calling this "offload"
is extremely dishonest and misleading.
