### 网络接口顺序
1. **物理网卡**：`eth0`
2. **本地回环接口**：`lo`
3. **Docker默认网桥**：`docker0`
4. **Docker自定义网桥**：`br-xxx`
5. **Docker容器虚拟网卡**：`veth-xxx`

## 网络统计信息
```Java
eth0:
RX packets 2377130 bytes 3372009777 (3.3 GB) # 已接收的数据
TX packets 322799 bytes 32328691 (32.3 MB) # 已发送的数据
```
这表明您的服务器已经接收了约 3.3GB 的数据，发送了约 32.3MB 的数据。
- RX = Receive (接收)
- TX = Transmit (发送)
