我好想买一个BF3啊啊啊啊啊啊啊
哎？你说我要不要放一个标题进去呢
先看看结构吧
跟BCM小太阳的PS225类似，这块BF2也是arm+自家的网卡芯片结构。bf2同时向host和arm暴露网口。
网卡分为了两种模式，DPU模式和NIC模式。
当服务器与 DPU 启动时，通往主机的网络连接将被阻断，直至 DPU 上的虚拟交换机完成加载。虚拟交换机加载完成后，默认允许主机通信流量通过。

向主机接口传递流量有两种方式：
- 通过 representor 代理将流量转发至主机（每份进出主机的数据包都会由 Arm 端嵌入式网络接口二次处理）；
- 向内嵌交换机推送流量卸载规则，直接放行该流量。
固件升级
抬手先检查一下固件，在线升级发现版本到24.43.1014。由于bf2新版本的固件已经转移到了BFB文件。所以要用另一种升级方法。
