        snps,reset-gpio = <&gpio2 RK_PD3 GPIO_ACTIVE_LOW>;
        snps,reset-active-low;

        pinctrl-names = "default";
        pinctrl-0 = <&gmac0_miim
                     &gmac0_tx_bus2
                     &gmac0_rx_bus2
                     &gmac0_rgmii_clk
                     &gmac0_rgmii_bus>;

        tx_delay = <0x3c>;
        rx_delay = <0x2f>;

        phy-handle = <&rgmii_phy0>;
        status = "disabled";
};

&gmac1 {
        phy-mode = "rgmii";
        clock_in_out = "input";

        snps,reset-gpio = <&gpio2 RK_PD1 GPIO_ACTIVE_LOW>;
        snps,reset-active-low;
        /* Reset time is 20ms, 100ms for rtl8211f */
        snps,reset-delays-us = <0 20000 100000>;

        phy-handle = <&rgmii_phy1>;

};

7.1.2. 板级的配置

kernel/arch/arm64/boot/dts/rockchip/rk3568-firefly-aioj.dtsi

&gmac0 {
    status = "okay";
    tx_delay = <0x39>;
    rx_delay = <0x2c>;
};

&gmac1 {
    status = "okay";
    tx_delay = <0x49>;
    rx_delay = <0x28>;
};

7.2. 如何使用双以太网

Android 双以太网口分内网和外网。

  • eth0 : 副网口,用于内网

  • eth1 : 主网口,用于外网

Android 系统Settings -> Network & internet -> Ethernet, 目前只能看到 eth1 的 IP 地址。

7.2.1. 查看IP地址

  • 双以太网口接入网络,可以通过调试串口或者adb来查看IP地址,比如

    ifconfig eth0
    eth0    Link encap:Ethernet  HWaddr b2:d1:83:54:0e:62  Driver rk_gmac-dwmac
            inet addr:192.168.1.102  Bcast:192.168.1.255  Mask:255.255.255.0
            inet6 addr: fe80::721f:ee30:f2a3:7bac/64 Scope: Link
            UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
            RX packets:189 errors:0 dropped:0 overruns:0 frame:0
            TX packets:135 errors:0 dropped:0 overruns:0 carrier:0
            collisions:0 txqueuelen:1000
            RX bytes:18349 TX bytes:7022
            Interrupt:41
    
    ifconfig eth1
    eth1    Link encap:Ethernet  HWaddr ae:d1:83:54:0e:62  Driver rk_gmac-dwmac
            inet addr:168.168.108.98  Bcast:168.168.255.255  Mask:255.255.0.0
            inet6 addr: fe80::641:354:8888:73fe/64 Scope: Link
            UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
            RX packets:2016 errors:0 dropped:0 overruns:0 frame:0 
            TX packets:41 errors:0 dropped:0 overruns:0 carrier:0 
            collisions:0 txqueuelen:1000 
            RX bytes:128098 TX bytes:4374 
            Interrupt:51
    

7.2.2. 连通性测试
