摘　　要：针对实现Linux系统的网络驱动的问题,提出一种模块加载网络驱动的方法。介绍了搭建P1010RDB嵌入式Linux系统的OpenEmbedded环境;论述了嵌入式Linux系统中网络设备驱动程序的体系结构;阐明了snull网络驱动程序设计具体步骤。在OpenEmbedded环境中,使用Bitbake构建snull软件包。采用模块加载方式将snull驱动模块插入到内核中,并对模块进行测试,验证并实现了两个虚拟主机之间的通信。In view of the Linux network driver problem, the network driven module loaded to the kernel was put forward. The working environment called OpenEmbedded was introduced. The embedded Linux was built on P1010RDB using OpenEmbedded. The architecture of the network device driver was shown. The steps to design the snull nerwork driver were elaborated. Based on the OpenEmbedded platform, the snull packages were built by the Bitbake tool and configured into the kernel as a module. The evaluation on the snull driver module shows that the proposed design implements the communication between the two virtual hosts.
