IB/hfi1: Enable TID RDMA READ protocol
This patch enables TID RDMA READ protocol by converting a qualified RDMA READ request into a TID RDMA READ request internally: (1) The TID RDMA capability must be enabled; (2) The request must start on a 4K page boundary and all receiving buffers must start on 4K page boundaries; (3) The request length must be a multiple of 4K and must be larger or equal to 256K. Each receiving buffer length must be a multiple of 4K.
