驱动程序通信:一旦phy_device通过net_device被注册到操作系统中,驱动程序可以通过net_device来与phy_device进行通信。例如,驱动程序可以使用net_device提供的API发送和接收网络数据包。 总结: 从phy_device到net_device的过程是将物理设备(phy_device)通过驱动程序和操作系统的抽象层(net_device)转化为可被操作系统管理...
该接口主要用来进行一个net_device类型的变量与phy_device类型的变量的关联、设置phy_device的状态为PHY_READY,并启动phy_device的状态机,详细处理流程如下图所示 1.确认phy_device是否存在(根据传递的phy_device_id,在mdio_bus_type中查找phy_deviec); 2.若phy_device存在,则进行net_device与phy_device的相互关联...
