IB/hfi1: Integrate TID RDMA READ protocol into RC protocol
This patch integrates the TID RDMA READ protocol into the IB RC protocol.
This protocol is an end-to-end protocol between the hfi1 drivers on two
OPA nodes that converts a qualified RDMA READ request into a TID RDMA
READ request to avoid data copying on the requester side. The following
codes are added in this patch:
- Send the TID RDMA READ request;
- Complete the TID RDMA READ send request;
- Send the TID RDMA READ response;
- Complete the TID RDMA READ request;
