经过内核的层层结构,条条框框,终于到了具体的驱动了,上面的函数使用的接口实际上是net_device_ops结构体的函数指针,还是以igb驱动为例,赋值如下: AI检测代码解析 static const struct net_device_ops igb_netdev_ops = { .ndo_open = igb_open, .ndo_stop = igb_close, .ndo_start_xmit = igb_xmit_fram...
在真正调用具体驱动的接口前,先发NETDEV_GOING_DOWN给到通知链,表示网络设备准备挂了,再清除__LINK_STATE_START标志,然后才调用驱动的ndo_stop接口,最后需要清除IFF_UP。 经过内核的层层结构,条条框框,终于到了具体的驱动了,上面的函数使用的接口实际上是net_device_ops结构体的函数指针,还是以igb驱动为例,赋值如...
从中可以看出,这个接口并没有从内存池中获取mbuf, 然后插入到软件发送空间struct igb_tx_entry。这个操作过程只有在真正发送报文的时候才会执行这个操作,例如e1000网卡发送报文的接口eth_igb_xmit_pkts就会执行这个将mbuf与描述符队列关联的操作。 3、中断掩码的设置 在eth_igb_start函数内部,会调用igb_intr_enable设置...
