写一个linux rgmii接口的网络驱动代码

在Linux系统中，rgmii接口的网络驱动代码可以使用如下方式编写：#include <linux/kernel.h>
#include <linux/module.h>
#include <linux/netdevice.h>
#include <linux/phy.h>
#include <linux/mii.h>
#include <linux/if_ether.h>
#include <linux/etherdevice.h>static int rgmii_probe(struct net_device *ndev)
{
struct rgmii_priv *priv;
struct phy_device *phy_dev;
int ret; priv = netdev_priv(ndev); phy_dev = of_phy_connect(ndev, priv->phy_node,
rgmii_adjust_link, 0, priv->interface);
if (!phy_dev) {
dev_err(&ndev->dev, "no PHY found\n");
return -ENODEV;
} priv->phy_dev = phy_dev; ret = register_netdev(ndev);
if (ret) {
dev_err(&ndev->dev, "register_netdev() failed\n");
return ret;
} return 0;
}static const struct net_device_ops rgmii_netdev_ops = {
.ndo_open = rgmii_open,
.ndo_stop = rgmii_stop,
.ndo_start_xmit = rgmii_start_xmit,
.ndo_set_rx_mode = rgmii_set_rx_mode,
.ndo_change_mtu = rgmii_change_mtu,
.ndo_get_stats64 = rgmii_get_stats64,
};static int __init rgmii_init_module(void)
{
return platform_driver_register(&rgmii_driver);
}module_init(rgmii_init_module);static void __exit rgmii_exit_module(void)
{
platform_driver_unregister(&rgmii_driver);
}module_exit(rgmii_exit_module);MODULE_LICENSE("GPL");
