Add logic to initialize protection information entities. Upon each iSCSI task, we keep the scsi_cmnd in order to query the scsi protection operations and reference to protection buffers. Modify iser_fast_reg_mr to receive indication whether it is registering the data or protection buffers. In addition introduce iser_reg_sig_mr which performs fast registration work-request for a signature enabled memory region (IB_WR_REG_SIG_MR). In this routine we set all the protection relevants for the device to offload protection data-transfer and verification.
