### 3.2 RDMA Provider Interface
```java
package jcifs.internal.smb2.rdma;

public interface RdmaProvider {
    /**
     * Check if RDMA is available on this system
     */
    boolean isAvailable();
    
    /**
     * Get supported RDMA capabilities
     */
    Set<RdmaCapability> getSupportedCapabilities();
    
    /**
     * Create RDMA connection to remote endpoint
     */

├── RdmaBuffer.java              - RDMA buffer management
├── RdmaChannel.java             - RDMA channel operations
└── RdmaProvider.java            - RDMA provider abstraction
```

#### 5.2 Implementation Tasks
- [ ] Research Java RDMA libraries (e.g., DiSNI, JXIO)
- [ ] Implement RDMA capability detection
- [ ] Create RDMA negotiation context
- [ ] Implement RDMA transport layer
