在linux中使用struct net_device结构体来描述每一个网络设备。同时这个用来刻画网络设备的struct net_device结构体包含的字段非常的多,以至于内核的开发者都觉得在现在的linux内核中,这个struct net_device是一个大的错误。 在本篇文章中,只介绍struct net_device中的一些字段,其他的字段在以后使用的时候再说。

1.分配一个网络设备函数,即分配一个struct net_device结构体: alloc_netdev(sizeof_priv, name, setup); 这个alloc_netdev()函数本质上是一个宏定义: #define alloc_netdev(sizeof_priv, name, setup) \ alloc_netdev_mq(sizeof_priv, name, setup, 1) ...

union thread_union { struct thread_info thread_info; unsigned long stack[THREAD_SIZE/sizeof(long)]; }; 当进程从用户态切换到内核态时,进程的内核栈总是空的,所以ARM的sp寄存器指向这个栈的顶端。因此,内核能够轻易地通过sp寄存器获得当前正在CPU上运行的进程。 [...
