以网卡 Fec 为例,网卡驱动在初始化 fec_probe 时遍历 dts 的定义,创建相应 struct phy_device 类型的设备,主要步骤为: 注册网络设备 net_device 申请队列和 DMA 申请MDIO 总线 创建并注册 Phy 设备 fec_probe(struct platform_device *pdev) ->structdevice_node*np=pdev->dev.of_node, *phy_node;// 获...

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) ...
