Subject: IB/srpt: Disable RDMA access by the initiator

From: Bart Van Assche <[email protected]>

commit bec40c26041de61162f7be9d2ce548c756ce0f65 upstream.

With the SRP protocol all RDMA operations are initiated by the target. Since no RDMA operations are initiated by the initiator, do not grant the initiator permission to submit RDMA reads or writes to the target.
