Abstract: Stack driver can lead to get through downright the path between the hardware interfaces and TCP/IP stack. The paper brings forward a scheme of implementing stack driver on Linux platform after having discerned its basic components and mechanism inside of the stack driver and following the principle of the hierarchy design of the Intel IXA software. It gives analysis at large and points out key technology in the course of the implementation. And the test of getting through hardware interface of light on Enp2611 evaluation board indicates that the implementation satisfies the demand in advance.

摘要： 彻底打通网络处理器光口到本地协议栈间通路需要协议栈驱动提供支持。针对协议栈驱动基本组成和内在驱动机制，同时确保遵循Intel IXA软件架构分层设计原则，该文提出了在Linux平台上的实现方案并进行了分析，指出了实现过程中牵涉的关键技术。Enp2611评估板上硬件光口打通测试表明设计达到了预先要求。
