In case the Target core passed transport T10 protection
operation:
1. Register data buffer (data memory region)
2. Register protection buffer if exsists (prot memory region)
3. Register signature region (signature memory region)

In case of protected transactions, we will need to check the

So be ready for RDMA_WRITE completions. currently we don't ask
