Data offset are intended to correspond to DATAO in NVMe/TCP and Buffer Offset in iSCSI. Previously for iSCSI, buffer offset had been merged to start block address, but passing buffer offset separately from start block address clarifies the logic more. On the other hand, for NVMe/TCP, passing DATAO separately from start block address will be critically important because DATAO will bave any alignment and will be necessary to use for not only reference tag but also guard computation. This patch adds data_offset to struct spdk_dif_ctx and adds it to the parameters of spdk_dif_ctx_init(). ref_tag_offset is also added to struct spdk_dif_ctx and it is computed by dividing data_offset by data_block_size and is used to compute reference tag. The next patch will use this change when getting DIF context in SCSI.
