上图来自 瑞昱半导体 (RealTek) 的 RTL8201F 系列网卡 PHY 芯片手册。按OSI 7层网络模型划分,网卡PHY 芯片(图中的RTL8201F)位于物理层,对应的软件层就是本文讨论的 PHY 驱动层;而 MAC 位于 数据链路层,也是通常软件上所说的网卡驱动层,它不是本文的重点,不做展开。另

sunxi-gmac.c 中把以太网的 phy 驱动的常规 probe 放在了 geth_phy_init 中,在网卡 geth_open 中调用,创建了 mdio_bus 设备,mdio_bus 在网络上博客描述是类似 SPI_Master 结构,spi_master 创建 spi 总线让 spi device 和 spi driver 挂接,mdio_bus 创建 mdio 总线让 phy device, phy driver 挂接,需要...
