04、PHY ID的信息

一、PHY ID查看

二、phy_driver 侧 id的定义

phy id的定义位置：kernel-4.14\drivers\net\phy\realtek.c

static struct phy_driver realtek_drvs[] = {
{  
    ...
    {
        .phy_id     = 0x001cc916,
        .name       = "RTL8211F Gigabit Ethernet",
        .phy_id_mask    = 0x001fffff,
        .features   = PHY_GBIT_FEATURES,
        .flags      = PHY_HAS_INTERRUPT,
        .config_aneg    = &genphy_config_aneg,
        .config_init    = &rtl8211f_config_init,
        .read_status    = &genphy_read_status,
        .ack_interrupt  = &rtl8211f_ack_interrupt,
        .config_intr    = &rtl8211f_config_intr,
        .suspend    = genphy_suspend,
        .resume     = genphy_resume,
    },
    ...
};
 
module_phy_driver(realtek_drvs);

三、 device 侧 id的存储

drivers\net\phy\realtek.c
