The ERNIC IP should be initialized and configured before it can be used for sending and receiving RDMA traffic. This involves performing the following steps in sequence:
1. ERNIC IP global configuration.
2. Memory region registration (for RDMA client application which share the memory region to remote hosts).
3. QP1 creation for sending and receiving RDMA connection management (CM) packets.
4. RC QP creation.
5. CQ creation.
6. Posting WQEs for RDMA operations.
7. Processing completions.
8. QP deletion.
9. QP fatal recovery.
