- [ ] Create RDMA negotiation context
- [ ] Implement RDMA transport layer
- [ ] Add RDMA buffer registration
- [ ] Create RDMA read/write operations
- [ ] Implement RDMA credits management
- [ ] Add fallback to TCP when RDMA unavailable

#### 5.3 Integration Points
- Create new transport type alongside TCP
- Modify negotiation to include RDMA contexts
- Update read/write operations for RDMA
