一、设备树配置

1.1 公共配置

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

&gmac0 
        phy-mode = "rgmii";
        clock_in_out = "input";

        snps,reset-gpio = <&gpio2 RK_PD3 GPIO_ACTIVE_LOW>;
        snps,reset-active-low;
        /* Reset time is 20ms, 100ms for rtl8211f */
        snps,reset-delays-us = <0 20000 100000>;

        assigned-clocks = <&cru SCLK_GMAC0_RX_TX>, <&cru SCLK_GMAC0>;
        assigned-clock-parents = <&cru SCLK_GMAC0_RGMII_SPEED>, <&cru CLK_MAC0_2TOP>;

        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>;

        assigned-clocks = <&cru SCLK_GMAC1_RX_TX>, <&cru SCLK_GMAC1>;
        assigned-clock-parents = <&cru SCLK_GMAC1_RGMII_SPEED>, <&cru CLK_MAC1_2TOP>;

        pinctrl-names = "default";
        pinctrl-0 = <&gmac1m1_miim
                     &gmac1m1_tx_bus2
                     &gmac1m1_rx_bus2
                     &gmac1m1_rgmii_clk
                     &gmac1m1_rgmii_bus>;

        tx_delay = <0x4f>;
        rx_delay = <0x26>;

        phy-handle = <&rgmii_phy1>;
        status = "disabled";
;

1.2 板级配置

kernel/arch/arm64/boot/dts/rockchip/rk3568-firefly-roc-pc.dtsi：

&gmac0 
    status = "okay";
    tx_delay = <0x4a>;
    rx_delay = <0x2e>;
;

&gmac1 
    status = "okay";
    tx_delay = <0x3e>;
    rx_delay = <0x32>;
;

二、双以太网的使用

此设备的双以太网口分内网和外网。 内网又称局域网（Local Area Network，LAN，是指在某一区域内由多台计算机以及网络设备构成的网络，无法连通外部网络；外网为广域网，又称公网，是连接不同地区局域网或城域网计算机通信的远程网，可以连通外部网络，如访问百度，搜狗。

• eth0 : 副网口，用于内网
• eth1 : 主网口，用于外网

android 系统Settings -> Network & internet -> Ethernet/Ethernet2， 可以查看主副网口的 IP 地址。

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：

• eth0（内网）：

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

• eth1（外网）：

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

2.2 网络测试
